Great Things to Do This Weekend: Pet Parade, Fine Art in the Park & Clean A Creek, Plus More

Who decided that May 19 and 20 would be so impossibly packed with things to do?

Los Altos Patch thinned them out to just a few fabulous ones. Each would have been enough to headline a single weekend by itself!

SATURDAY

10 a.m. The Pet Parade is back in its usual spot, after a year-plus of construction downtown knocked it from its usual May slot.

9 a.m. to noon Clean a Creek. Saturday is National River Clean Up Day. Greentown Los Altos and Acterra, among many many others organize local clean ups of the waterways in our communities (The Clean A Creek site features a great "mockumentary" of the life of a plastic bag). Meet at , bring a bag lunch, and be ready to get dirty (and have fun).

10 a.m. to 5:30 pm. Fine Art in the Park, the premier fundraiser for the Los Altos Rotary Club, spans two days at Lincoln Park. Bring your checkbook or credit card, and a camera for all the great people-watching, and ideas.

10 a.m. to 4 p.m. . This is in neighboring Menlo Park, but if you've ever wondered about the science of earthquakes and wanted to see what goes on at the U.S. Geological Society campus, this is the time to do it (unlike Sunset's annual June bash, this triennial event means you'll have to wait if you miss it). Demonstration, activities, and fun stuff galore. On Sunday, from 2-3 p.m.,, a bluegrass band, is among the many musical groups performing all weekend. Free.
