In addition to the outdoor trails, there's a wonderful greenhouse at the Boyce Thompson Arboretum. Inside are a large number of rare and exotic plant species - again, cactus, succulents and lilies.
I love stone buildings. And stone fences. It's something about their permanence and solidity, I think. Plus they look really cool. And they're made of a natural material.
I noticed there are heaters in the greenhouse, but they weren't on at the time. The ambient temperature was about 60 degrees F. A little chilly, but comfortable.
I was the only person in the greehouse for the 20 minutes I was in there. Too bad I didn't bring an ukulele - it was very relaxing and would have been a great place to practice a bit.
