So far I've ridden out 8AM to commute once, but will continue commuting. On weekends I've ridden out mid-morning to mid-afternoon for grocery run or pleasure ride on our scenic trails. I've also ridden out in the 6-7 pm time frame to practice riding my bike in the early part of my cycling "career", then just to have some fun if it's still light out and the weather is good.
I've slowly conquered my various fears as a beginning cyclist (fear of descents, fear of cars, etc.). Next is fear of riding at night, because it's going to happen if I keep commuting to work on bike, when DST ends and the days begin to shorten again in the fall.
