I have stored my three kayaks in my garage for the last four years. They stack well but they take up too much floor space in the garage. I would really like to keep my second vehicle there this winter. I know a lot of you keep your kayaks outside. How do you do it? I don't want to just put them on the ground and cover them with a tarp. I've thought about building a rack but I don't want to attach it to the house or the fence ( too many flower beds and shrubs). Any ideas would be appreciated.
