I found out about Fairground CG's due to a breakdown. the local police escorted me to one.
I then started looking for them. I use them all the time. I love em. They are usually empty so you are not packed in like sardines like at most CG's and I love the peace and quiet.
Even if they say there are no sewer hookups that just means at the site. There are ALWAYS a dump station on the grounds. You just have to look for it. Usually alongside the barns.
They are all not just dirt lots. Using them ONLY during 'off' season is a must. Never when the Fair is in town!
Des Moines Iowa is my fav, always make a point of stopping there.
Here is the view of Iowa's gold capped capital building from atop my Fairground CG site.
My Toad enjoying the view
The entire 2,000 site CG all to myself! Full hookups and a fantastic shower facility.
Stopped for the night ended up staying a month! :C
