Mel - thank you for the description between the two in use. I was really hoping my wife could use the weehoo as I was going to have a rack on my bike that I could connect the kazoo too. I guess we could always get an extra rack for her bike and an extra seat post mount for the weehoo for mine and have both on both bikes so we could move back and forth depending if everyone is going or not.
At 3 years old next spring I don't see a ride behind working for longer rides. I could look into a used trailer on craigslist but I think she would outgrow that quicker. I'm sure that would be more stable but I'm guessing the drag would also make it harder to pull..... Not yet sure what to do for her.
