I haven't done this before but I'm told this is a nice launch site when the Ohio river level is right. I confirmed with the Corps of Engineers that this weekend will be a good time with moderate current. Here's a link to a description: http://www.fallsoftheohio.org/clark_cabin.html
Based on the naturalist at Falls of the Ohio State Park we will probably launch from there, though we can look at the George Rogers Clark Park boat ramp too. The two sites are very close. My cell number is 608-2572. See you there!
