I did a gimmick rally once. Came in second The amazing part was my co-driver had never rallied either and we finished almost 45 min late. Our second place was entirely based on having all the questions answered correctly. We missed a turn near the end and spent all our penalty time trying to find it. We finally went to the next point we could locate and didn't miss any clues :)
I put together a gimmick rally for a LSMC weekend event I tried to host. Nobody wanted to go to East Texas and 1st Monday in Canton, so it was a waste.
The biggest problem I have with rallying of any kind is time (no pun intended). I might be able to squeeze this in before I have to report for duty to the Solo Dogs detail that is hosting dinner Saturday night.
Somebody else wants to see what this is all about - I might be more likely to go.
