Good luck, Vonn.
If repair people there are anything like the ones around here, you'll be lucky to have a/c by January.
Some air conditioned ideas:
Spend a little extra time at the diner. You know the waitresses love it when us oldsters hang out and ***** about nothing for a couple of hours. Don't forget to tip well. 25¢ should do.
Head to the local mall. You can toddle around for a few hours, suck down an Orange Julius or two, maybe a Cinnabon, if you can take it.
Lots of benches to rest on, so take advantage. Maybe make a few disparaging comments about the obnoxious youngsters.
Letting your cane slip and trip people, while you pretend to nod off, is always good for a chuckle.
However, sitting in front of Victoria's Secret for an extended period is not a good idea!
The idea is to stay cool. The back seat of cruiser warms up pretty quickly.
Back to the diner for dinner and more coffee. Should be a whole new crop of waitresses to annoy.
At this point, if they haven't fixed your a/c, you'll have to suck it up and get a cheap hotel.
You can usually find a local place for less than $20, if you don't mind a few inconveniences. So long as the a/c works, you're good to go.

In the morning, you can start over again.
Just watch the smiles in the diner when you walk in.
