Total Sports Experience (in Gates) is on dealchicken.com today. One of the options they offer is the Micro Sports session which is usually $60, so you can buy it for $30 (I think they are 6 weeks long). June did the soccer, and I think other than R being a little young, it was a good experience, right?
They also offer a birthday party option which may be something winter bday people may be interested in.
