Ice is a simple combination of water and cold temperatures, just like fire is a simple combination of oxygen and a dusty attic full of old Teen Heartthrob magazines. Skate across the cold terrain with today's Groupon: for $12, you get two entries to open skating and two pairs of skate rentals at Ice Town in Riverside (up to a $26 value). Discounted rates are available based on age or military membership.

The pristine frozen pond at Ice Town spreads its crystallized arms wide for open ice-skating sessions seven days a week. Skaters surrender their droll shoes and strap on a pair of blade-bottomed skates for an enjoyable afternoon of open skate, which extends the rink to all skaters looking to sail across a smooth surface untarnished by potholes, sewers, or neglected meteorites. This Groupon entitles customers to a day of open skating; on days when the open skating sessions are split into two blocks, customers may skate, take a break when the rink closes, and then return to the second session for the remainder of the day.
