The site of the Spring Fling is Holmes Bend Marina Resort : Holmes Bend Marina Resort - Houseboating on Green River Lake in Kentucky Houseboats (> river end of the lake)
The "floating cabins" are at Green River Marina : Floating Cabins – Green River Marina (> dam end of lake)
Green River Lake is a good lake for "numbers" of keeper Crappie (9" @ 20/day/person) ... and also has Muskie (2 species), Walleye, White Bass, and the regular catfish & panfish population.
There are two Crappie guides that I know of at Green : t.slabseeker (Tim Marple) & KyTeacher (David Jones)
You can get a good idea of the layout of the lake, facilities on & around the lake, and surrounding towns by going on Google Maps or Google Earth .... the lake is located in South Central KY.
There are two very good hospitals in the area : Taylor Regional Hosp. in Campbellsville & Ephraim Mcdowell Regional Med Center in Danville (about 40mi NE of Campbellsville) .... or there's Lake Cumberland Regional Hosp. in Somerset (about 45mi East of Columbia).
