The kids are out of school, there's no point trying to get any work done at the office (everyone you need to reach is on vacation, anyway), and the natives in your home are getting restless after a lot of feasting and home-bodying.
What to do?
Why, the answer is crystal-snowflake clear: Haul the fam up the hill for a romp in one of the dozens of SNO parks that dot the Sierra.
Be advised: They're likely to be crowded on this holiday weekend, and space is on a first-come, first-served basis. For information on SNO-park types or locations, or where you can pre-purchase a permit, call the California Department of Parks and Recreation SNO-Park hotline at (916) 324-1222.
