Traverse the entire Playground crag in either direction. Amazingly beta-intensive. I never did the entire thing, but I know it's been done. If you're willing to go high, you might be able to make this a bit easier, but the classic traverse stays within a few feet of the ground the entire time.
There are several sections that are easier for tall and/or flexible climbers. It's not pumpy, as there are numerous no-hands rests. Expect weird, greasy cruxes and semi-dynamic *foot* moves in many spots. Old school bouldering at it's finest.

Traverse the Playground.

You don't even need a pad. Best landing ever, and your feet are rarely more than 2' off the ground.
One quick comment - the only person I know who has done this is Jon Butler, back in the mid-90s. He knew the traverse like the back of his hand. He might well have gotten the first ascent, I don't know for sure, but it's definitely not the kind of problem most bouldering folks are willing to spend the time to work out.
