every body is going crazy over the tiapan lately, i walk past a huge one nearly every day at work sunning itself, and am usually no more than 2 feet away and this dude is huge,not once has it even looked at me as i lead the horses past, he just slithers back into his hole, then is back 20 minutes later, we never bother him and he never bothers us, i will take a photo today and post it, he has just shed and is a beautiful shiny black.
