That's what our youngest grandson who's 18 months old calls a motorcycle..."Ta-caa". At least that's the way it sounds to all of us. His Daddy has a Ta-caa and Papa has a Ta-caa. When our son and daughter-in-law came to the house early one evening a couple of weeks ago, they had just bought the above crotch rocket for him at Target.
The Beemer GS he calls "Papa's Ta-caa". He has another one that's a cruiser he calls, "Daddy's Ta-caa". They say he carries them around a lot.
And occasionally he likes to pretend to be a Vespa pilot. It looks like riding might be in his future. This gives me mixed feelings. Of course it's hard to imagine him riding at this age. My natural reaction is protection. He won't be 16 for quite a while so for now we'll have fun with the Ta-caas.
