I Had No Idea These Existed Anymore!

OMG if this doesn't bring back childhood memories! When is the last time you had a Slush Puppie? Growing up I was either treated to a Slush Puppie, a Slurpee or an ICEE on road trips! 1 was like a slush, this Slush Puppie was icy like a snow cone. One thing I cannot remember however is...

where would be find Slush Puppies? Which convenience store could we walk into and find them? I cannot remember for the life of me! Surely they were a part of your childhood too? Also, of the 3, which was your fave as a kid?
