This has some promise as long as someone has the wax and the time
here are the pipes. If you want to grind them you will need to wax them I think and you have to grind TOWARDS the camera because the pipes are bent at one end.
a pretty crazy bank if you want to do some Jimmy Boyce style flip to tail on them
there are plenty of small gaps like this all over the car park.
These are the man-made synthetic marble benches, there are 6 in total (some are behind me) they grind nicely BUT KEEP YOUR EYES OPEN I got chased after taking these photos so ideally go in a big group. The benches themselves are a decent size, the floor is OKAY but is a bit bumpy but not enough to effect you.
