If you’re worried about being able to squeeze into that dress or suit for the office holiday party, but there’s no way you’re giving up an extra helping of Mom’s peach cobbler, fight off those extra pounds this weekend with a heart-pumping hike. Each week, the Sierra Club guides members and friends along trails that range from easy and family-friendly to downright strenuous. Starting at 9 a.m. this Saturday, November 24, you can really work off the gravy with a strenuous 17.5-mile, all-day hike that will cover nine trails. Call Paul at 964-9002 for info. Or Sunday morning at 9 a.m., take the kids out to explore the UCSB Lagoon and bluffs area for an easy three-mile stroll. Call David at 705-3025.
