My daughters liked riding in the trailer when they were young, too. I didn't understand why they didn't get bored, but they didn't. One of them told me the bike goes faster than the car. I figure that's because it's lower and it has no suspension, so those factors make it feel faster.

They're too big to fit in now, at ages 21 and 18. Ah, memories. Maybe when I'm old and decrepit, one of them will tow me in a trailer.
