Assuming "tn" meant "tonight"

At least back from where I'm from in Fort Lauderdale, there were a lot of car shows on Friday nights and a few Saturday mornings. Fright nights tended to be the younger crowd with hydraulics and lighting and stereos (usually at a Costco or Walmart lot) and Saturday mornings were the classic cars with gorgeous iridescent paint jobs 😍

The same seemed to be the case in Atlanta and in LA. I wonder if it's just a common Friday night/Saturday morning thing across the country?
