Dealing with winter. I live in the rural upper Midwest, where winter can hit -20 with whiteout blizzards, week-long power outages, and car-burying snowdrifts. I’ve seen too many people move here from warmer places and think “I guess I’ll buy a warmer coat and a snow shovel”, rather than “I should have a backup generator, a backup heat source, a few barrels of spare fuel, a month’s worth of stockpiled food, and at least two different pieces of heavy snow-moving machinery tested to be in good working order”.

During AC season, 71 during the day, 68 at night. Geothermal FTW.

Bug zapper flyswatter. Like you can buy at Harbor Freight for a few bucks. It might not be a terribly effective solution to the overall fly population, but in terms of grim-bloody-vengeance-per-dollar, it’s one of the best investments I’ve ever made.

Specific subs that don’t exist on Lemmy, especially Q&A-type subs with no equivalent (or very few members). Things like AskPlumbers. It’ll just take time to build those communities here.
