I loved A&W, I met one of my longterm ladies friends there
me & a buddy used to go to get (this would be in like 78-79)
chocolate/chocolate dipped ice-cream cones, freaken' delish
in our (my) 68 & he had a 69 RRs or in my 68 Charger R/T
way back when, in Concord Ca.
We pulled in & asked where's the nearest KFC was, (it's right next-door)
broke the ice
she laughed & we struck up a long conversation
she ended up, dating me & then living with me, in my house for 4 years...
Vicky, I miss her 'some'
I loved the rootbeer floats too, fresh cooked burgers, fries etc.
not really fast food, car hops were always decent looking ladies
I liked the service & atmosphere there
Sonic was sort of the same too
We don't have either anywhere near here
I never tried the 'swamp water' or what the OP called it...
