temporary garage

Here's another vote for Shelter Logic. I've had a number of these things over the years, the SL holds up the best. 2-3 years on the top is about right, but it's pretty cheap to replace. Sidewalls last a lot longer. I use a 5-gallon bucket filled with water and a bit of bleach at each leg to hold it down. I also string parachute cord lengthwise on the roof at the 1/3 and 2/3 width both sides, to give more support to the roof. If I don't when it starts to rain (and in the PNW, it's all about the rain) the roof bellies badly and holds water. The paracord helps keep the roof from bellying between the frame members and holding water/snow. For snow, I have to get out there early and often to shake it off. Otherwise it again bellies the roof and makes a mess. However, this is a reasonable cost-effective way to go.
