I am from the Great State of Maryland, but have canoed in Florida on Singer Island and on a beautiful river about an hour west of Jacksonville that I can't remember the name of. If you need some information about some of the Mid-Atlantic Rivers look me up.
An hours west of jax may have been the st mary's. nice river, i did 5 days on it last year. we have a number of good ones, including the springs in central fl. have to admit it never occured to me to paddle around singer island (maybe its just too close to home).
We are heading to the green river in sw utah this year. will miss the bw!
If we make it to mid-atlantic will be sure to check in with you.
