I have to share this with you guys... A new place opened up recently quite close to where we live. We are just off of the Roanoke River, and the place is called On the Greenway for the 'Greenway' paved walking / biking trail that runs beside the river. Anyhoo, the place rents tubes and bikes. Some of the bikes have the little kid thing attachment (not a seat but a buggy) and while driving by one day I exclaimed ' We should rent one of those and take the dogs!' Needless to say all I got was eye rolls and 'that is the worst idea I've ever heard'.
I, however, think it would be a hoot!!!
