You need some spontaneous fun and it's gonna be warmer on Saturday.
Come meet folks from the local CrossFit scene and run around like a kid.
I suggest basketball, tennis, or minimalist shoes. Running shoes are probably not a good idea (ankles tend to roll in them when you're cutting from side to side).
Equipment will be provided. Bring cider if you're the sassy type.
Cost is $15, register and pay here: http://sportsfest.crossfit26.com/
The hockey rink is located on Strassner Drive in between Hanley Road and Brentwood Blvd. You'll find a map on the Sports Fest website.
