SalsaMTB, I'm with you! I'm riding more than ever, loving the cooler air (though not the lessening daylight). It's as if my body is craving the opposite "of getting ready for hibernation." As it's paying off, I'm not questioning why. The shorter daylight hours will eventully put an end to all but my weekend rides - then I'll spin. No hibernation for latelate - that was the PREVIOUS 40 years!
