How Close Is Too Close?

As the weather warms it bring out many creatures that have hibernated through the winter. A lot of these are amphibians and reptiles which provides some interesting photo opportunities. When encountering these creatures I try to get as close as I can to give a different perspective to what I'm photographing. Here are a few shots of a reptile that some of my fellow photographers said I was nuts to get that close. I also included a picture of a frog for those who are squeamish about snakes.
