^^Well, it's good that you've never visited. Your life will be all the richer for it. Okay, some places are okay...but the High Street is so depressing: ranges and ranges of pound shops, charity shops and cut-price clothes and book (with pictures) shops. The street market is interesting on an anthropological level as a chav's foraging ground.
Ever heard of Rowner? Notorious Gosport estate, (now finally being demolished at last!) which had the distinction of being the only place in the south of England where property prices were in freefall at the peak of the boom, LMAO! I had the dubious pleasure of living there, on and off, for a while. Became quite acquainted with the Rowner Rabbit (rats) and the well-known Rowner Carnival (the procession of police-cars, paddy-wagons, black-marias and wailing ambulances that would tour the area on regular occasions)
Funniest thing that sticks in my mind about Rowner is when Gosport Borough Council attempted to give the place a bit of an image makeover by rebranding it as 'Rowner Village'!
Southsea's cool though. Quite like it there. A few good comic-book and collectables shops, a model shop with the strangest proprietor you can imagine, and an amazing bookshop where the overheads are so high for the owner that he's just scattered the books all over the floor, and you can pick your way through them. Luv it!
