There is a great little outdoor shooting range just north of Silverthorn. If you exit I-70 and head towards Keystone ski resort right before you get there (to the resort) on the east side of the road where the city dump is there is a great little range. A 50 yard pistol range, 100 yard rifle range with 4 benches and a shotgun range. The city has prisoners from the jail clean up on the first Monday of every month. If your close stop by and throw a couple shots down range.
