You should find a group ride that goes a serious distance. My buddies wife ever year rides to the Mackinaw Bridge from..... I think Ann Arbor. But they only do so many miles a day, they all stop to camp in the same spots, It seams really organized.
I met a guy in the UP a month ago on a bicycle. He was from New Orleans. He said it took about 2 weeks to get there, and he was headed to NY and down the eastern seaboard back to Louisiana.
Hopefully your new goal is to rest for the next few days. It's going to be really hot. Be careful out there if you decide to ride. My bike is still taking me on short trips. It will be parked for the time being, I don't like humidity or anything over mid 80s.
