never here in vegas and believe it or not when we lived in depere we didn't use it much on the fox/longtail. only on 4th of july when coming home after fireworks to keep the girls warm.

back home in boise, we used a heater in the early spring and late fall on some of the colder afternoons but found a hot water shower to be much more beneficial to keep the wetsuit warm. used that quite a bit.
