Openers...Search the board. There are some really good threads out there. Or just look for stuff on Eugene's gym (he has a sweet set up). But, to save some time. Check into a set of rings and a place to do pull ups. Then check into bumpers and a bar. There is a thread for KBs that arrived recently. They look like a good deal. The whole structural questions are not my bag. I am the Anti-Norm Abram (Measure twice cut once toss away that peice of wood and start over). Keep the air moving for the stink. Ceiling fans or big box fans. After a little more thought. Since summer is coming. Get the rings and KBs and head to the park.
