If you have time and patience and do the scouting, even from a full sized vehicle with some decent optics, you can start to figure out some places where they like to be late season, even close to some vehicle access points. Early season, if you are too disabled to be able to walk much, you wont have much luck on bucks, so put in for doe tags.
I know you have rifles that shoot a long way, I've seen your posts before, so if you can walk a mile or even a half mile you will be as good as most other hunters anyway. Even if you can't walk a lot, you still need to do YOUR own homework and figure the deer out. Took me 2-3 years here to get some "places", and yes anything bigger than a 18" 3pt takes a lot more luck and work, but those smaller bucks are not hard, not last year, and certainly not this year. We all have bad days, but based on your posts I would guess you either have much more than most or just need to put in more time figuring it out. Deer don't like every ridge....
