Nice to see that there's another Lightning running around in Sonoma County - I'm in Santa Rosa. I have yet to see another one anywhere in the wild. These numbers are similar to what I've been getting, too - took it to Lassen the 1st week I owned it and got 2.3 overall. Most of the trip was over 100 deg F (July). I get 2.4 driving up the coast (slower speeds). 2.7 or 2.8 in town.
