I started my punting career by street punting and did so for many years, long before the internet, aw etc and the only other source was the local rag or a couple of parlours, both of which only had shit options.
Street punting was cheap, anonymous and easy (providing there were girls out). BUT it was only ever about feeling horny and finding a quick shag. Years ago the police had better things to do than catch a few kerb crawlers but times have changed. They got CCTV and ANPR. Comments about fuck the police are lunacy and don't think for one minute you'll be able to out smart them. If they catch you, you're screwed ! I just hope anyone caught street punting doesn't have much to lose because they come down inordinately harshly. They will do you for punting on foot too !
I haven't even considered street punting for years now, indies are far better in every respect. Even factor in 40 quid for a quick shag with a street girl and it's the equivalent of at least 200 quid an hour and far less enjoyment and less safe. The close calls I've had all came from street punting, looking back I must have been stupid to get into the situations I did.
I say let others ask about street punting, it is punting after all and it's not lowering the tone in my opinion. My advice will always be don't do it, book a 30 min session via AW.
