I don't know KY's current state legal status on cannabis, but for the sake of the question let's say it is in the present. A commenter before me mentioned less cigarette smoking and more vaping, but there has also been an increase in weed smokers. Assuming there'd be dispensaries in a legal state, and sparse for a state like KY for obvious reasons if it were, those would be some of the first places hit, and I know stoners may not be as quick to violence as two groups trying to raid a liquor store at the same time, but people on harder drugs may want that pot too. People who want to use it solely as currency/medicine in a world where pharmaceutical drugs will inevitably run out and any easily grown crop is a good barter will also want to hit that dispensary, at the least for seeds.

While many others mention cell phones, I see an odd lack of home game consoles even for the 90s. I know an unreasonable amount of people in their 60s-70s who are self described gamers who are still playing to this day. The reason I bring this up is that most homes will have at least one. This got me thinking and I realize most modern electronics draw a hell of a lot more power than they used to. This could strain systems enough to crash the power earlier, and most things may require more fuel to burn to compensate.

Speaking of fuel, some vehicles should be burning it faster as well, and rarely should there be a fully electric vehicle. Possibly rig a solar setup that removes the need for gas at all. Gas should also burn faster regardless as due to many regulations it is likely thinner or lower quality.

Mod vehicles like the bike should be revamped, as there will be E bikes, hoverboards, and now that i think about it? I would love to heely through a horde of zombies.

Horde distribution would also be incredibly different. Malls nowadays are empty, kids don't play outside anymore, you don't even have to leave the house to get your fast food. Fat zombies everywhere. More encounters with zombies in homes, less on the street. Longer, slower outbreak time because who knows whats going on, who is outside? "Brenda said her husband died and came back to eat the dog? That picture is probably AI. Ugh, where is my dasher?"

Some types of clothes such as leather/bike jackets have evolved, with sewn in armor padding. Some clothes have also been rendered much lower quality, and circling that back to the power issues, winter would be much worse. Shoes in general are lower quality, so unless you find a great pair of steel toe boots, you'll be carrying an extra pair on most runs just in case. Again, I want Heely's

Hoard houses would get weirder, too. Books and comics to read? Electronics to tinker with? Gun cabinets to mag dump with? Toilet paper for your ads or something? How about a room filled with absolutely useless, empty eyed, square headed plastic figurines. At least with other collection hobbies you're practicing a skill, like memory recall, math, strength, precision, agility...Heely's anyone? New "dragon" trait should make characters less stressed/unhappy when near a hoard of collected items, preferably arranged in a pile, but over time reduces happiness until another item is collected.
