“I live in a very conservative area, and I am seeing a very large number of Biden/Harris signs, way more than Hillary! signs in the last election.”
Then, by definition, you do NOT live in a very conservative area...
I live in a (sadly) very liberal area - mostly a bunch of aging hippies and failed artists, as far as I can tell - and there are more Biden signs (slightly) than there were Clinton signs, but there are *way* more Trump signs than there were in 2016.
Something I noted in 2016 - the houses with Clinton signs were the ones not giving out Halloween candy, with a single exception. I don’t think I get to do the same evaluation this year, for obvious reasons!
My town is very conservative (with more Trump signs than street signs) but I do drive a couple of days of week through a town that sounds like yours, with _exactly_ the same situation as you described—many more total signs than 2016, more for Biden, but a lot of Trump signs too when there were no Trump signs in 2016.
My state is CT which is a lost cause for Republicans, but it is nice to see the Trump supporters are not afraid to show their standard Trump signs/flags and also other creative hand made signs (latest one was “Say No to Quid Pro Joe”).
I live in St George county in Florida...goes red every election. I see only 1 Biden sign, and no Trump signs at all in my sub-division community of 300 newer homes.
