Anybody knows a place that sells cheap safety equipment or maybe even climbing equipment?
I need to fix the barn roof but our barn is very tall and the galvalum is pretty slick - only got the nailheads to hang on to with my toes I guess.

So I'd like to get a safety harness somewhere just in case... would be ironic if was back to riding horses and then brake my back falling off the barn! Who sells that sort of thing?
