There's a mind-boggling huge outdoor store near us called Galyans.  It's the size of a warehouse and has two stories of shopping in it.  Things like hiking boots, camping supplies, bows, sporting equipment and so on.  At the other end of the store is the wall where you can practice climbing.  The wall, I think, is four stories high. 

This pictures shows the peak of Brian's climb.  It's not that he found the climbing too difficult.  He freaked out when he looked down.  His brothers suffered similar fates.

If you do manage to make it to the top, and many do, you ring the bell and everyone claps!
