Without wanting to sound like a wet blanket, you shouldn't be going without proper maps / mapping equipment or an intimate knowledge of the lanes you intend to drive. The chances of you going 'off piste' are great and that doesn't do any of us any favours.
If you have memory map I can send you overlays of routes, but you really should be checking that the routes you intend to drive are not TRO'd before you even leave the house.
As I said, I don't want to sound like a miserable sod, but it's people hitting the lanes with no clue and upsetting land owners that ends up with them shutting for the rest of us.
Obviously if you have checked for TRO's lanes on your proposed route and have a mapping system or extensive local knowledge I appologise.
