I used to keep track of everything....... but then I realized that I remembered them anyways..... and never looked at them..... I think that it would be a good idea for anyone who has a lot of snakes..... but for someone with only 4..... one of which I will not keep...... I don't think there is a real point...... but what I do keep track of is the local population...... I take pictures of and measure every one that I find..... but that's only because I have a small pop.......
