I'm not sure how you can get enough gear in for a solo diy without driving there anyway, unless you are hunting out of a hotel. Bow/Gun case, Big duffel limited to 50 lbs, a cooler can hold up to 50 lbs of deboned meat. I'd need an entire other bag for camp gear as well.
I decided a while back I will drive to all my fall hunting trips. Its a haul and adds a day or two, but if I tag out early I can leave early, I'm not limited on what gear I can bring, and my processor in El Campo Texas is completely bad assed, I prefer to put ice blocks in the cooler and let it age a day or two then take it to them, rather than some local who doesn't know what the word "hot" means.
Another option, I have heard of people who hunt moose out east doing, is keep your round trip ticket, if you get a big bull down, just cancel the 2nd leg and rent a uhaul and drive it back. The numbers I saw showed several hundred dollars saved vs. shipping, but moose are bigger than elk also.
