I love the fall. trails and road sides are simply spectacular this season - best in recent memory. The horse farms, the farms, the tree lined roadsides, the single track covering over with autumn colors, the crisp air refreshing you I could go on and on. basically when the snow forces me off road I go, when the wind and temp let me its back on road, otherwise its the trials for me in the winter and fall.
I also like the brief time that we get for dawn rides. I ride nearly every morning and most all weekend days, the fall weekend days are the best, but that pre-dawn / dawn ride in the fall in the cold weather is just great to do before work - nothing can get to me with that behind me and in front of me every day.
one thing that I think people forget about standard time (when we " fall back " the clocks) if that for the very same reason it gets colder it gets darker. If we didn't set the clock back, the most we would wind up with is light until abotu 6PM EST and it would be dark unitl nearly 8AM!! that would not suit anyones work day as even light unitl 6PM makes it hard to get a good ride in. Winter means shorter days regardless of daylight savings /standard time clock manipulations.
