In my 2007 preseason scouting, I have found numerous Southern Red Oaks with good acorn crops.
If you are looking for a handy field guide that you can throw in your pack the next time you are out scouting, I recommend either or both of these books. I use both because often one will have a better photo or illustration than the other and two points of reference always helps. If you don't want to spend the cash for two books, I'd give a slight edge to the Peterson's Guide.
Next, we'll take a look at the chestnut oak.
