Midwest hangers - firecaptain53 and I are going to meet at Siloam Springs State Park(park info) in west-central Illinois on Friday, March 19th. If anyone would like to join us for all or part of the weekend you're welcome to meet us there.
We plan to backpack to their backcountry camp sites and stay through Sunday morning. It's a few mile hike to the camp sites and there is a creek nearby. Saturday will be spent lollygagging and probably a dayhike around the park to check out the lake.
Siloam Springs is located between Springfield, IL and Quincy, IL:
