I love Vernors! It makes everyone else in my family choke.
Valomilks (like Reese's peanut-butter cups but with marshmallow instead of peanut butter)
Tak-A-Boost/Drink-A-Toast (a weird New Jersey drink--it comes as a concentrated syrup and tastes kind of like flat Dr. Pepper. You eat pretzels when you drink it. My mother is from New Jersey and she brings gallon jugs back whenever she visits her family.)
Those little metal cap bombs--do kids play with caps any more? We had six-shooters, too.
We've had Teaberry gum (and Black Jack, the licorice gum) as long as I can remember. We used to get it at REI before it went yuppie.
