A couple of months ago I built a little track for myself as I was getting a bit bored with going round and round and round my garden so if anyone local fancies coming and even just having a quick whizz around, PM me and we can sort something out
Haven't got any photos of it but a video of the layout at least is

Edit: Track is in North West Kent, Meopham to be precise!
