Pythons and Boas are illegal in San Francisco (within city limits), so that's a definite no-no around here. I have a fenced patio they roam around sometimes, but only when I can supervise very closely - because they could easily find a hole to slip through, and end up in my neighbor's yard. Not good! The other day I answered the door with Delilah around my neck, because I didn't have time to put her back... luckily the delivery guy just said "sweet snake."

Short answer to the OQ - no, I don't go for walks with my snakes. It's simply too risky in too many ways...
