|Usually climbing buildings is frowned upon by police, security, the general public and your mom. MORE INFO >>>|
Go to the back of the IGA building. Look for the large metal staircase. Once you're on top of the stairs, use the hinges/doorknob and railing to ascend the additional 6 ' to the actual roof. Easy, and short.
NOTE: It would be possible to go from the backside of the railing and jump to a cat-grab on the wall next to the stairs. This has not been done yet.
Get down by lowering off the edge of the roof and finding the holds with your feet, or just dropping onto the large platform.
No crash pad necessary. (May want a crash pad for the optional cat-grab)
