Since I just finally figured out how to install my Pet Cool (which is a heater too), I am very interested in a winter adventure.
Patoka Lake is a little drive from St. Louis, but it is an easy one along I-64.
I may not be able to convince my wife to come,

but I like cold weather so I am willing to make a solo voyage. I have friends in Evanston, so I might be able to do a little visiting on the way there or back.
Raprap, do you have a link to the campground handy? I found a whole bunch of campgrounds in the area, but I don't think I found the one you are referring to.
All the best...
