I started kerb crawling 20 years ago in Bristol. It was very easy back then as there was no police and loads of girls (mainly British) available. I did all sort of stuff with them, mainly in my car, but sometimes in their flat or outside in the bushes. From 2010 it started to change, there were less girls and more police. I got nicked in 2013 and I had to pay a fine of £200 and attend a course.
Today, kerb crawling in Bristol has become virtually impossible.
I also did a lot of kerb crawling in Birmingham, Manchester, Edinburgh and Glasgow. The girls I picked up were almost always British, often pretty and friendly.
Of course I got a big fright on a few occasions, like in Manchester were I got mugged, but generally speaking, I very rarely got myself in trouble and 99% of the girls I picked up were fine.
I think people who enjoy kerb crawling are people who like to take risks. Basically, you can never be sure how your punt will turn out to be, which can be a bit stressful and scary. But it's thrilling as well.
Having moved to Leeds, I can now pick up girls without fear of arrest thanks to the tolarated zone.
Mind you though, the RLD is now closed because of the pandemic and the lockdown.
