Matthiessen State Park seems like it is about as close to the Appalachians as one can get in IL. We did a lot of up and down while we hiked through the dells area of the park. Then we climbed up out of the canyons and took the Vermilion River trail out across more prairie-like terrain. Total distance hiked was around 5.5-6 miles. It really seemed shorter because I was talking with different folks almost the whole way!
I did pack a winter load, but only packed 1 liter of water and two days food. It all fit quite nicely in the zPacks Blast 30. Total pack weight was only 18 lbs. I was surprised, but then I realized that while I did swap out my light top quilt for a heavier BA sleeping bag, I also wore a lot of the clothes that I had been packing through the summer months. So I think I'll be able to keep my winter weight at my earlier goal of 22 lbs or less. This is very encouraging!
