The Clear Creek Sportsmans Assn hosts IPSC/ISPSA matches on the fourth Sunday of every month. Set-up begins around 7:00 and the match start time is 10:00.
The weather up there can be dicey in the winter months so be sure to check your email or here about a match cancellation *before* you leave in the morning. Or, if you hear about the match being canceled, please post it here to make sure others know as well.
