So, every year there is the Register's Annual Great Bike Ride Across Iowa (RAGBRAI).
http://ragbrai.com/It's starting in Sioux City this year. There are thousands of people who ride across the state on bicycles. It lasts a week. Anyway, the hotel rooms in town were gone the day the announcement was made that it starts here, so residents are asked to host riders.
My brother has friends from Illinois who do the trip every year. They have a bus, and tents etc. So he asked if I'd mind them camping in my yard. After I said yes, I found out there are 25 people in their group!!! Then a couple friends asked if they could camp here too. I figure what's the difference between 25 and 30, so.... on July 24, there will probably be close to 30 people camping in my yard, grilling out back and having a few beers.
It should be a blast. Plus it will be a huge incentive for me to get the rec room in the basement totally finished. It won't take much, but if the weather turns bad, I'll need a place for 30 people to go.
