add in parking in downtown SF $10
A few seconds search turns this up (and I was surprised how cheap parking in San Frannie is based on a trip to LA several years ago.
"Average prices offered by SpotHero include $20–$32 for commuter parking, $18–$35 for weekend parking, $20–$40 for event parking, and $30–$50 for overnight parking"
and
"Some areas have demand-responsive pricing, which can put parking rates over $10 per hour"
My wife and I went to a wedding in Cambridge MA (near MIT).
Parking was 50 bucks for twenty four hours (since we stayed overnight).
I had not visited any city in years (since I retired) so it was quite an eye opener.
The good news—none of my other young relatives live in cities.
