I have a 16 foot + long strong back available for free in Toronto if someone wants to pick it up. It is built from 3/4 inch plywood as a 6"x6" beam. Two 8 foot sections telescope tegether for easier transport. The connecting piece is 36" long so it can be extended longer than 16 feet. Let me know if you are interested. The logical place to post this notice would be on the Bear Mountain forum, since it is local, but the life of me I can't seem to register on that site.
