I'll be spending a couple of days each way flying out and back from LA (it's a 5000 mile round trip). The arrival isn't too bad unless you get behind someone flying really slow out of Lake Parker (single file, no overtaking).
It's the next biggest thing to Oshkosh but on a more modest scale.
The seaplane event is at Kermit Weeks' fantasy of flight field on the Thursday at Polk City, about 15 miles up the freeway from Lakeland.
Carry sun, rain and tornado protection. Hopefully not a repeat of last year!
