Yeah, I have a gartersnake that hurls himself against the front of the viv when I walk into the room. Then he gets all frantic until he's let out. After he's out, he carefully examines every square inch of my hands until he's satisfied there is no food (I handfeed him except when he gets guppies), then curls up in my sleeve and sleeps.
Honestly, why would anyone expect a snake to go through a maze for no reason? If it's cozy and the temps are right, why move?
I would be interesting to take a bunch of breeding season ready male corns and put them through a maze with a female corn in season at the end, without the female having crawled through the maze before. That way they would have to go strictly by air scenting and memorizing which way is the right way. I bet (I mean, um, hypothesize) that they would do just as well as any rodent.
