I don't take my snakes outdoors unless it's for a quick picture in natural light. And I've only carried a couple of them to the pet store, but that was to have them probed back before I knew how to do it myself. I don't see the point in risking your animal's safety just so you can get your kicks. You're taking your snake out of his warm and dark hide to parade him around in the sunlight or through the aisles of an air conditioned store. Not very pleasant. If he's more energetic outdoors he's most likey just eager to find a new hiding spot.

My biggest peeve is seeing people walking around in public with a large snake around their neck. If something spooks that snake and he constricts out of panic, guess who's air and blood supply is going to be cut off? About a month ago I went into the pet store for feeders, and they had just hired one of the employee's daughter to work in reptiles. She had brought in her dad's 6 ft burm in with her and was carrying it around draped around her neck. What a great way to teach responsible pet ownership to your customers, huh?
