That's great advice!Only one point means your options for units are so limited that I'm afraid you don't have many options to be picky over. The good news is antelope habitat is generally easy to get around in.
Honestly though, if this is truly a dream you've had and you are genuinely concerned about your physical ability to pull off the hunt, paying special draw prices to hunt a marginal Wyoming unit with crowds of hunters might not be worth it if you're willing and able to go guided.
If I were in your shoes I'd seriously consider private land options in New Mexico. You can find a trespass style hunt and possibly get a deal on buying two tags instead of one, hunt private with a chance at good bucks and maybe the ability to glass from the truck some. I'd look for DIY or unguided though, I think having a guide over your shoulder would take the fun out of pronghorn hunting.
That's just my advice for if you go guided, I think it's still very possible for you to draw a tag in Wyoming and get on some antelope.
