Just The Tip Of The Iceberg...
Are you aware that only 1/4 of the SP scene in Victoria takes place in outdoor venues (eg, rock bay and "track")? That means that approximately 75% of the SP's in Victoria work indoors, in escort agencies, massage parlours, and as independents; this is not supposition but a statistical fact backed up with independent research done by government, social service and non-profit organizations, including current and former Service Providers themselves. Therefore, if you really want to make the observation that there is a disappointing selection of "unappealing faces" night after night, you're going to have to put in a little bit more effort than merely driving around along darkened streets (while an unmarked police car lurks in a back alley, taking down your license plate #). Whatever your reasons are for sticking to this mode of "shopping", you're missing out on alot of incredible talent that can be found in indoor venues. If you're not finding what you're looking for, just remember one of the definitions of insanity: doing things the same way each time, yet continuing to expect different results. Ain't gonna happen...!
Good luck!
