Summer = free for me, other than working on my parent's waterfront home.
Winter Storage = $13.00 per foot for winter, not per month. Includes nothing but a space. Winterize myself, no shrinkwrap..I use a winter cover.
Next summer I'm going to take down sone trees, widen my driveway and keep the (Hopefully) new boat here, most likely year round. Can't put a lift at my parent's house, and I don't want to keep the next boat in the water. That's going to be tough to get used to though. I'll probably dump it in every Friday night, and leave it in until Sunday.
