Arie,
We always launch off of Summerlin, just before you get to the toll booth on the Sanibel causeway. It's a great spot, it's free, the area is in a grass flats and you can sail pretty easily out of there. I thought about launching at Bunche Beach but I haven't been down there in a while so I don't know if I can get the boat to the water even on beach wheels and at this time of year when it's so crowded I'm afraid to drive my truck and trailer down there because if the parking lot is full I couldn't turn around and would have to back the truck and trailer a couple of miles to a spot where I could. You can e-mail me at
[email protected] and I will give you my phone number. Maybe we can get together and go sailing.
