Bay Area seniors know that much of the meaning of life can reliably be found in the musings of the late cartoonist Charles Schulz. Many of his pearls of wisdom that issued from the mouths of Linus, Sally, Snoopy et al are currently on display until July in “Peanuts Philosophies” at their Museum and Research Center (?) in Santa Rosa. There are more activities here than you might have imagined including lectures with astronauts discussing Peanuts’ connections to the NASA space program. Who knew? Seniors $5.
