It's a wonderful feeling to really enjoy your classes! I'm glad for you. I too decided to take advantage of my school's physical education options this semester, since I have some wiggle room in my schedule for once. I signed up for a swim class. I never learned more than one stroke or had any formal instruction. Why not, right? Rock climbing is a great time. It'll do a lot for your grip and finger toughness :p
Hahah yeah, can't wait for my first class! And once you get the accreditation, the prices is seriously laughable. It's 50$ for 4 months compared to 80$ per month in climbing gyms. Startup cost is a bit steep but fuck it, i've been wanting to for a really long time so now's the time to try. I didn't realize how good we have it price-wise until I looked into it. I wish I did sooner.
