I have stored my boat at Becker Storage… well in Becker – north of Elk River. My 1775 boat costs me $150/season. It’s a bit of a haul for you but depending on what you’re used to paying might be worth it. I have stored there for probably the last 10 years. I think this upcoming weekend is probably the last to get your boat in. Good luck.
I’m looking as well for my 19 foot Warrior. It will be out early as the River gets going early. Hastings is where I live, so South Metro or Western WI would be nice!
