For the first time in a while, I checked out my old London hunting grounds, and there seemed to be quite healthy pickings.. There were some long-timers who hiked their prices, but for the most that I had peviously seen advertised, , they were roughly where they were back in Dec, 2019, and seemed to tbe currently active if breaking lockdown is your thing. There were a few newbies, too. My anecdotal thoughts were there were more (of the SP I tend to go for) operating than there were then.. More or less around the Heathrow, Twicxkenha, Kingston, Surbiton areas...
