I would like to take a 2-day tour of this route but have found a lot of conflicting information online. Could someone tell me what the surface is like on the two canal trails and how it compares with other trails such as the Katy, GAP, or C&O? How much is shaded in June? Also, are there any closures other than the western-most section of the Hennepin? What bridge is recommended across the river in Joliet? Finally, I'm thinking of camping at Illini State Park. Are the better options on that part of the trail? Thanks!
