The Clay County Fair - the World's Greatest County Fair - from the Clay County Fair in Spencer (the annual September fair that has been designated the World's Greatest County Fair - drawing 300,000+ visitors over its nine-day run to agricultural exhibits, livestock shows, carnival rides, and entertainment that make it the largest county fair in the United States - the fair's scale, organization, and quality have earned it international recognition and a visitor base that travels from across the Midwest) to Spencer's 1931 fire recovery (the catastrophic fire that destroyed most of Spencer's downtown on June 27, 1931 prompted one of Iowa's most unified community rebuilding efforts, resulting in the Art Deco commercial district still visible today).

Organized by the Spencer Commercial Club in 1917, the fair held its first modern event in September 1918, just six weeks before the WWI Armistice, drawing over 30,000 people. Today it draws more than 300,000 guests over nine days each September, with an attendance record of 334,575 set in 2013, and features what’s billed as the largest farm machinery/agribusiness display of any fair in the U.S. or Canada, spanning roughly 35 acres. The fair’s 1931 grandstand, built for $45,000 to seat 5,000, still stands today. In 2013, the fair partnered with Iowa Lakes Community College to set a Guinness World Record for Largest Science Experiment.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Clay County District Court, 3rd Judicial District 215 West 4th Street, Spencer, IA 51301 (712) 262-4335
Clay County was founded in 1851, named for Colonel Henry Clay Jr. The 1901 Clay County Courthouse (Classical Revival, National Register of Historic Places) is the county’s fourth.
Step 1: figure out which path applies
Iowa has its own comprehensive probate code (Iowa Code Chapter 633) and has not formally adopted the Uniform Probate Code. Iowa offers several tracks depending on estate size and complexity:
Distribution by Affidavit (“very small estates”) – for estates where the gross value of personal property is $50,000 or less and there is no real estate, available 40 days after death under Iowa Code § 633.356. A sworn affidavit is presented directly to banks and other institutions. No court filing is required.
Small Estate Administration – a simplified probate process under Iowa Code Chapter 635 for estates with a gross value of $200,000 or less, with reduced notice requirements and court costs compared to full administration.
Regular (Full) Probate – standard administration through the district court for larger or more complex estates, which can be independent (unsupervised) or supervised.
Supervised Administration – closer court oversight, typically used for contested estates.
Step 2: filing for formal probate
File a Petition for Probate of Will and Appointment of Executor (if there’s a will) or a Petition for Administration (if intestate) with the Clay County District Court.
The court admits the will (if any) and issues Letters Testamentary (with a will) or Letters of Administration (intestate) appointing the personal representative.
Publish notice to creditors; under independent administration, creditors generally have 4 months from the date of first publication to file claims.
The personal representative inventories assets, pays valid debts and expenses, and – under independent administration – largely acts without ongoing court check-ins.
After the creditor period closes and debts are paid, the personal representative distributes assets to heirs or beneficiaries.
File a final accounting/final report; the court closes the estate upon approval.
What it costs
Personal representative fees are capped by statute at 3% of the gross value of the probate estate (excluding life insurance) unless services are itemized; attorney fees follow a similar framework.
Recording fees at the county recorder run about $7 for the first page of a document and $5 for each additional page.
Typical timelines: Distribution by Affidavit – a minimum 40-day wait; independent (unsupervised) probate typically closes in 6-12 months, with the 4-month creditor period as the primary timing constraint.
