I actually had to do this as part of a school project in 6th grade - but for 3 days. I chose beef jerkey but also wanted to do strawberries, so when I finished the 3 for beef jerkey, I did 3 on my own of strawberries. Now I would probably choose some sort of fish - tilapia, roughy, halibut - something.
Beef jerky for 3 days
... I could do the strawberries though
I've only done it on car trips to Key West, but I love the area, Mallory Square, conch fritters, fresh coconut ice cream, the piano bars, etc... I love Key West.
