I uploaded a photo journey of the Hennepin canal trail on Flickr, which you can see on the "Bicycling" tab of this website. I also uploaded a longer, more detailed set that surveys the locks, bridges, and sights on the Hennepin (for now you can find on the "Facts" tab; Ed.--the survey was moved to the "Canal Photos" sub-page of this website, under "Canal Information", above), to give an idea of what you would encounter on a bike trip or paddle journey (I have a lot of photos of the bridges and locks for the latter).
On another note, there is still no easy way to connect from the Hennepin trail to the I&M trail by bike. I didn't get any photos of the roads that connect the two but I did find a link about it on the "crazy guy on a bike" website . The Kaskaskia Alliance Trail has been proposed to form a trail link between the Hennepin and I&M trails but at this point it is still in the planning stages and the only means to connect the two are busy roads with little or no shoulders in parts.

This blog weighs in on topics such as long-distance skating, the Illinois canals, cycling, and a variety of related (and occasionally not-so-related) topics. I'd like to correspond with others interested in skating the Hennepin and I&M canals.
