Anyone interested in checking out one of the Computrainer-based classes at this place?

You bring your own bike, slap it on a computrainer and go for a ride with up to 15 other folks with simulations of hills/etc. There's a screen showing everyone's data (power, speed, heartrate, etc). Not sure how the HRM works, as the thought of strapping a 'used' heart rate strap around me and sweating like a pig seems a little gross to me. Apparently a day pass is $20. I wouldn't mind checking it out while the conditions outside still suck for longer rides.
