Ah yes, details!
You can pay a drop-in fee of $18 for each class, or Athletic Playground has monthly membership plans and punch cards.
As far as the open ropes session on Fridays, you might still need to pay the $18 drop-in fee or be an Athletic Playground member. I'll have to get back to you on that one. I'm out of town for the rest of July so this will start in August.
I intend to do another open ropes session at Lake Merritt, which will be free, in August. I'll post the date here when I figure out when I can do it, or you can check out
