Hey all you climbers, I just found out about this Groupon for Planet Rock Climbing Gym.
It's for either "$39 for a one-month membership" (current members) ($95 value)
"$19 for one adult starter package including one day of unlimited climbing. ($42 value)
Good in Pontiac and Ann Arbor Gyms. http://touch.groupon.com/deals/planet-rock-detroit-rock-climbing-company-7
This Groupon will end 1/24/2014 at 12:00 am.
