Yes we have a big fatty binder where all of the information about our snakes is kept. not only is it a great way to keep track what's been going on with the snakes, but it has all of the information for each snake so if we ended up stuck out of town for a extended amount of time, a family member or friend would be able to reference it to care for the snakes. Another thing we have started using is Evernote, which is a free program where you can take notes or pictures on your phone, and then access them from any device. That way if we think of something we need or breeding ides etc... we write it down and later can look at those notes from any computer or phone. i also take photos of business cards and then file them in evernote so i don't lose them later.
