my name is brian thomasson and i'm attempting to travel the entire st johns river by boat. i'm planning to start in jacksonville, where i live, and end up somewhere close to the head waters. marshbunny directed me to this forum hoping that someone could answer a couple questions for me. i was going to start my trip with a john boat (25 hp) and end with an airboat. the problem i have, is where i need to switch from the john boat to the airboat. can i get all the way to camp holly with a john boat? if not, do you know how far i can get with the john boat? one more question...i do not have polymer on the bottom of my airboat and i'm worried about stumps, rocks, etc....do i have to worry about these boat benders in south end of the st johns? any help would be appreciated. thanks! --brian
