Do what we do.....
One of my mowing clients has a 6 x 6 tristeel with nothing in it, except my camper trailer.
Your bound to have someone nearby that will have a free garage. (target old people without a car)
I offered to mow their grass for free in exchange, but they still pay me anyway. (i did it again this week)
The funny thing is, i'm so sure of its safety, when mowing this week, i didn't even put my face against the window to see if it was still there.
I did however, let them know i'll be picking it up in a fortnight as we prepare for Fraser.
the other good thing about old folks, is they are always home too.
