Free: Contests & Raffles.
This is a good year to draw certain areas by applying in the special draw, due to huge increase in price this year. So due to your circumstances that's what I'd be looking to do. Not sure which one you did for elk but if you're willing to spend the money for deer and antelope in the special draw you could probably draw some good areas with the points you have. I don't think too many people are going to be spending $1200 each for deer and antelope. In your case I think it would be worth it. At least for your dad's tags. Maybe he could apply in the special and you in the regular to keep the cost down.
Since you mentioned other states, how about Utah with a landowner or guaranteed tag. Might have to run the finances. I've never done that so not sure about the specifics, and doesnt help your WY points much. Herds are in much better shape there and application window is still open
I don’t have any input on the hunt since I’ve never hunted Wyoming, but I’m sorry to read about your dad. If it’s not out of line, I might suggest you make the trip, even if you can’t get tags. You can still do everything minus pulling the trigger, and it could make great memories for you your dad & your daughters
