It's when people throw large rocks to see how far they can make them go.
Just kidding. It's a type of climbing where instead of going up you stay closer to the ground. Sometimes you just climb short routes or sometimes you do more lateral climbing. It's a great workout and you don't need to use ropes so you can get a lot of climbing in, in a shorter time.
Knott - They should let you boulder all you like if you're testing out shoes. Maybe they even have a pair that you can rent and you could take them to a climbing gym. There must be a million gyms in Seattle.
I miss climbing. I should start again. Maybe after IM. Believe it or not, I have a bouldering wall right outside of my apartment and I almost never use it.
Living life like there's no tomorrow.
