This past weekend, I rode the Illinois section south of the Lewis and Clark Confluence tower just north of East St. Louis. I used the Vertices site to create a route, then rode the route as closely as I could. In several places, I was unable to follow the route because either the MRT is on bike-only paths, or in one place there was a gate.
Curiously, I never saw a single MRT sign anywhere in Illinois.
That said, it is a really great ride, except for a few sketchy sections through East St. Louis. the ride along the river to the south is absolutely gorgeous, and on a hot day if the conditions are right, one can get a few blasts of really cold air past the limestone quarries.
Anyone want to work on the Central and Northern sections of the Illinois MRT?
