WanderingRed, it sure sounds like ya'll are going to have a lot of fun, and it does make me happy that your wife wants to be part of the hunt.
One thing that I forgot to mention is that a small pair of binocs can also be a good thing to have with you. There will be times when a squirrel is up in a big tree and hiding on a limb. They are almost impossible to see with even young eyes, so binocs can be a help.
Do try to pick a day with low or even no wind. Many days will be like that early in the morning. If you get lucky enough to have a morning like that, the wind won't be whipping limbs around. What that means is if you see a limb or leaves moving at a distance, it's probably one or more squirrels causing the movement.
And you've made me hungry too...
Have fun and watch out for snakes.
