whereis.com cruises are boring!
Make your own!
Basically, jump in the car and drive! Have someone sit beside you to write detailed instructions as to which way you turned on what street etc etc.
If possible, get someone else to drive it after you have writen the map to make sure its enjoyable and the map is accurate etc.
Then type it up, print out copies and hand them out at the meet point.
Id be happy to help out normally but i dont have much spare time at the moment sorry. Good luck with your cruise mate
