What's in a name?

[nightrider]

My name derives from the fact that I love to ride my sled at night. When I was younger, I used to extoll the group to go for a nightride after everyone had settled down for a relaxing night in front of the fire. My family has been in Winter Harbor since the 1940's. I ride with Treerider and Loafrider. I'll give anyone a free nightride if they can figure out where those two monikers came from. Replies from the Treerider and Loafrider don't count.
