Armybrat,
I don't have any information on the units. But your best move would be to get ahold of the biologist for the area you want to hunt. It may take them a little while to get back to you, but it has been my experience that they will point you in the right direction depending on what type of hunt your looking for. I saw that you were interested in a 3rd season tag for 41,42,421. My buddy and I have tags for 421 4th. From the research that I've done, this looks to be a very promising hunt. If you can get a tag for the right price you might not want to rule 41,42,421 3rd season out. I would shop around a little, I'm sure that there are some out there for less than $1000. Good luck.
