Suwannee River.  If you are down South, try the Suwanne River Wilderness Trail.  Google the trail for information.  They have free river camps about 10 miles apart.  These have 16ft by 16ft screened camps and they have bathrooms with hot showers.  Definitely not wilderness but a very pretty river and you will enjoy it.  You will see several beautiful springs along the river.  If you want whitewater, put in above Big Shoals.  It is up to a class 3.
