How to go rock climbing
It made me
concussion! 
"i went twice. i fell, and got a 3-day concussion. great experience though."
How I did it: my school's gym has a rock wall, and it's staffed. so there are open hours a couple days a week, and i just went whenever i had time. i only went on the beginner trails, and i fell when i reached for the last one to end the beginner trail. my guide didn't break my fall like he was supposed to, bc he was busy ogling my roommate.
Lessons & tips: use chalk!
