I LOVE this facility! I started out at the east side YMCA, but that place is a bit of a freak show-everything from the barbell dropping barbarians to the lady on the elliptical machine who sounds like she's orgasming for the entire 45 minutes she's on that thing.
I needed to make a change, so started attending the Y in Sun Prairie. New, clean, no obnoxious dudes making a racket (or ladies), I never have to wait for equipment and the place is extremely tidy. The staff members are helpful and friendly (they are at the east side y, too...to be fair).
Anyway, kudos to the Sun Prairie Y.
