I go up watnall brickyard just off m1 j 26 if you drive down the motorway your bound to of seen the four big chimneys??? it's private land and the only way to get on is along a bridleway and over bridge unless the main gates are open (normally on sundays sometimes sat aswell) then you can drive up. heres a good ariel of the site (think you have to click the arial tab??) doesnt give you too good a perspective though looks flat but its not on different levels etc

now that looks like fun!

yer it is fun, it is illegal to ride there i believe though so at your own risk but saying that i go up 2 or 3 times a week and have never seen any coppers up there????¿ and it wont ever become an official site as the link may suggest the council and police are against the idea
