I meant to mention this sooner, but (being me) I forgot. Sometimes I have the attention span of a gnat.
When I was at the Hyannis rodeo, I needed a snack, so I went to the concession stand to see what $3 could buy me. I finally settled on what was being called a walking taco. My first question was if it had onions. The answer was no, so I ordered one. Hamburger meat, sour cream (if requested), Fritos and cheese were served in half a Fritos snack bag. I wish I had grabbed a spoon instead of a fork, but I managed pretty well. Personally, I would have called it a travelling taco just for the alliteration, but whatever the name, it was awesome!
