We'll be visiting the Lyle Center, Cal Poly Pomona, 9 to noon this Saturday.
It will be hot, dress for blistering sun. Bring water and someway to protect against the sun. Most times for this field trip, after we've seen the center, Orchid and I and all who want to, go down the hill to the 'farm store' where we buy a loaf of bread, some sandwich fixins and have lunch in their patio. Everyone is welcome to join us.
There's a lovely map here.
