Biking - Struggling Westbound, then Sailing Home

It's another sunny, relatively warm November day, almost 50 again. The only catch is that the wind is blowing at a steady 20-40mph, gusting to near 50. What better day for a bike ride? Since the wind was coming down the Mohawk Valley from the NW, I decided to ride upstream and upwind for 10 miles, then turn around and enjoy the free ride home. This was a tough fight on the outbound leg, where it was hard to even maintain 7-8 mph at times in very low gears, not to mention staying in anything resembling a straight line. But, oh, the ride home! I hardly ever dropped below 18mph, and even kept it between 20-25 for one stretch. This sure beats the crap out of riding on the trainer in the basement!
