IMO a mileage event imposes very stiff rules such that it detracts from the fun, or else it is too easy to cheat. Another detractor is that no two cars are the same, so winning doesn't take as much skill.
My word is definitely biased, but a time/points based rally is all fun with very little in the way of rules. Alternatively, just prepare a map for people who want to take a drive in their free time. Either way, a night rally would be very interesting /images/graemlins/wink.gif.
If you decide to piece together any kind of route, give me a buzz and I'll share the secrets of the 03 rally with you.
Cheers, and great prez BTW.
