My labmate Noah came back from this year's Ant Course with a wonderful treasure trove of skills and experience that I intend to mercilessly use for my own advantage. He also came back with a copy of Brian Fisher and Stefan Cover's long awaited Ants of North America: A Guide to the Genera. It is beautiful! It includes keys to 73 genera, 180 color images, and a nice glossary of useful terms. Plus, it comes in a handy portable size and appears sturdy enough to last through a couple of field seasons, at least. You can pre-order them from Amazon for $23.07. You should go do that right now. Git.
