Harrow used to be such an incredible hotbed of value for money SPs about 8-9 years ago. I lived in Kenton and got to enjoy several visits with Intensepleasure4U aka Cindy, Predator Viktoria (seriously, the hottest woman I've ever seen) and a few Hungarians, Polish and Czech girls whose names escape me. It's a shithole in general now, and the punting scene reflects that. Best to head a few zones inward or outward to find the quality.
