I find punting in Italy to be very opaque with a lot of dogs and B&S profiles (obvious porn actresses, etc).
If anyone has insight into punting in Italy please share. 
I think things have changed recently in Italy with regard to policing of WG's.
You used to be able to drive from the southern end of Lake Garda to Verona and see scantily clad women looking for punters.
I did on a couple of occasions stop and sample the delights which I must say were very good, but its 10 years since I was last there.
There also used to be a few girls work around Verona station but again this is a long time ago.
It would be interesting to know if these ladies are still allowed to work.
