I am always surprised when people tell me they are afraid to ride at night. Fear stops people from experiencing so many things. Riding in the city at night can be very peaceful. Fewer cars, more space, less noise.
Night riding isn't about carrying a ton of groceries or getting to work on time. Just grab your purse and hit the road.
The only hurry is to make sure you get to the pub while there is still a seat to be had.
Or maybe it is a gallery opening you are headed out to. A show of impressionist photography perhaps?
Maybe it is just to burn off some energy from the day. It doesn't really matter. Give it a try if you never have before. You will never have to worry about a valet scratching your car ever again!
