Traveling, concerts and dining out all cost money. There’s nothing like a cold, hard look at your bank statement to get you down. What can someone do to overcome empty-wallet syndrome? Attend free things! This weekend, the Marin Agriculture Land Trust hosts its 15th annual Landscape Art Show and Sale to benefit its mission of preserving Marin farmland. For two days the show exhibits pieces from 40 artists, most Marin-based, depicting the pastoral Marin countryside. They say the best things in life are free, so you might as well take advantage of it Saturday–Sunday, May 19–20, at the Druids Hall. 4499 Nicasio Valley Road, Nicasio. 2–5pm on Saturday; 10am–4pm on Sunday. Free. 415.663.1158.
