Garage Pointer aims to be the AirBnB of garage rentals. It was started last year by a punch of experienced gear heads one of whom I know and have traded gray matter. They would love help in passing this along to anybody you know who wants to rent their garage. There really hundreds of people signed up waiting to rent space. Check out the site details too. Insurance is required through the site for both parties to protect their interests. And unlike AirBnB who triumphed over concerns of people staying in your actual house, this relationship only requires access to your garage.
