Second, love the username - I wish it were mine now. Very fitting, for me anyways.
3rd, My wife didn't want ours in the garage either but I just put it there one day and it's been there ever since. She complains now and again but I just Jedi-mind trick her. You could always try that.
I have several friends that have not yet taken this advice and rent storage units. I know one said he was paying $100/month (I choked). I can't imagine it being a lot less then that and what a waste of cash...
Maybe you could buy your wife some Jewelry and say she could keep it if you got to put the boat in the yard at least - or give her $100 cash every month, then take it away to pay the storage unit - that might drive the point home!
Do you have any friends you can take advantage of? I have stored several peoples boats in my yard over the years...
Other than that, I got nothin'
