We are driving to Cooperstown early Wednesday morning. This now seems like a bad idea. a)do we have to do further ArriveCan info for our "trip" across the border to Hertz in NY and then back to our hotel on the CA side? b)this also seems to set us up for another chance at random testing. I know some here say that there is no testing at land borders but that directly contradicts the information on the CA govt website. Land testing was never suspended even when the random air arrival testing was briefly suspended earlier this summer. I am now wondering if we should just stay in Canada and pick up our car Wednesday morning. The reason we were trying to avoid this is it's my understanding Uber/Lyft will not drive you across the border. We need to leave early Wednesday, so trying to cross the border on foot (with all our luggage for a 9 day trip) then get a Lyft to Hertz on the NY side seems like a giant pain. Any advice on that end (assuming I'm not in a 10 day quarantine)? I'm paranoid enough that I'd cancel this trip if it wasn't too late.

You can also pick up the rental car in Canada and drop it off in the US, although it might be more expensive.
Two weeks ago, when I was in YUL at the enterprise-rent-a-car desk, and I noticed an American tourist who did exactly that. The agent told him that they're giving him a rental car with a US license plate, since he was goint to drive to the US and return it there (at least that's what I could gather from their conversation).
