My commute for the last 7 years has been only 40 miles each way. Prior to that, (for ten years) it was 67 miles each way, but I didn't have fuel-saving motorcycles then, just the old 1990 Toyota 4x4 and the 1984 T-bird, which is why the truck has 358,000 miles on it and the T-bird died at 254,000. At different times I have had commutes of 16 miles one-way and 8 miles one-way, both if which I did by bicycle as much as possible.
