If it's actually “hundreds” of boats as you mentioned, the only place I know of that size near LaBelle is Indiantown (which is on the other side of the lake). I spent six months on the hard there and saw perhaps a half dozen 42’s or Manatees stored or being serviced, but the great majority of Snow Bird Krogens are in and around Stuart.
River Forest has space to store 300 between their two convenient facilities in LaBelle and Stuart, but unless there has been a sudden surge of Krogens, I can’t recall seeing huge numbers there either. Maybe Covid has changed this as well, but I haven’t seen mention of it on the Krogen Cruisers site.
