I spent all my childhood in greater KC and enjoyed the glory era of the Royals from 1976-85... I turned 15 and moved to Texas - in late September '85. My dad had gotten transferred and Mom was finishing her last year of nursing school, so she stayed behind and lived in Westport. Sure enough the Royals come back from 3-1 series deficits vs. Toronto and St. Louis, and my mom gets to enjoy the celebratory party.
First surprise everyone gets in KS is that it's NOT FLAT. People think of Kansas and it being flat as a pancake. Well the western half is just a long slow flat imperceptable climb to the Rockies, but the eastern half is very hilly, as is Missouri.
The WWI Memorial and Museum in KC would likely be of interest to anyone in the UK. It's very interesting. The Truman Presidential Library is neat too.
I mentioned Fort Worth BBQ in a different thread, but I cut my teeth on KC BBQ (Gates, Arthur Bryants, and Haywards),which is more pork/less beef than what you find in Texas. I hold both in equal regard, with Memphis BBQ just behind and all three way, way ahead of that crap they serve in the Carolinas.
