I stopped by at Beaver Park, and they look pretty good and are 1/2 way between Avon and Vermillion, approximately. That's a pretty good location, and they have the $400 for the remaining season for a 20' boat, and run about $800 for the season. I may do the docking next season, and will finish this season as a trailer boater. It's only another 15 minutes from Miller Road, where I usually launch, to Beaver Creek.

thanks
