Let's make this simple, taking leagues and such out of the question.
If you're at a sports equipment store and your looking to play soccer or ice hockey starting from scratch.
What you need for soccer:
Soccer Ball-30 bucks for a good one
What you need for ice hockey:
Ice Time-(if not playing on a pond ect.)
Ice Skates-60 bucks per person for decent skates
Stick-40 bucks per person
assuming you play without gloves and a helmet......
I've got Bieber fever, and the only cure is Zac Efron.
