I am just beginning to formulate an idea for a 3 year mileage challenge, similar to this years but with some twists.
Nothing really sorted yet, I am having some discussions with Fermentum about how to develop the idea.

The reason that I am mentioning it so early this year is that I want to guage whether people would be interested and, if they are, to give them advanced warning to find a coin with a special meaning to them to use.

For instance, if we go ahead I will be using a Jeep geocoin as I drive Jeeps.

Once ideas have developed I will post more on the subject.
