And for you "I hate those new fangled gadget thingeys"
From the South East take A1 North past Newark to A6075
Turn right onto A6075 continue on until you meet A57 to Lincoln
From the North take the A1 South til you get A57
Turn left A57 to Lincoln
From West Midlands (Birmingham) take A38 to Derby
then A 52 past Nottingham to A46 North to Newark
Then take A1 North to A6075 Lincoln
A57 takes you right past the site, which is on the left, exactly a mile after the 25p toll bridge - yes I did say 25p Toll Bridge, about 7 miles outside Lincoln
