The "Motorcycle Nights" that I go to are in Lowell, MA. All types of riders there, from your stunters to your chromed out busas to your regular harleys to bobbers, bmw's, etc.
I usually go for a ride before hand, show up & hang with anywhere between 10-30 of my close riding buddies, check out the other more interesting bikes that show up and whatever type of entertainment & sponsors they have there that night. Then we go out for Chinese food.
It's more about getting together with my riding buddies that I don't always get to see/ride with on a regular basis than the bike night itself.
It's a good time... Especially Chaps Contest Night
