Fun! thanks.
I spent 2 weeks in Paris last year, served to convince me I AIN'T a city boy. But it was sure fun!
We saw several families (hubby, wife, 2-3 kids) out riding those 24/7 busy streets, they'd just take a lane and cruise along, drivers took it in stride and didn't run over the 5-yr old on the kiddie bike trailing behind... Amazing.
