There was a thread some years ago by two cyclist who road from maybe Minnesota to Florida. They even rode there on antique road bikes maybe with shift levers. They also posted a Youtube video of their adventure. They said they ate Poptarts during their ride for energy replacement.
So I would like a link to their thread here and Youtube Video.
Shift levers. Lol I like shift levers. Its about 1500 miles. Doesn't seem like too much. Must be funny to watch the videos. Pop [censored] really aren't going to cut it. I guess they wanted convenience food. I'm going to guess it was under the Road Cycling section.
