If you go to Netherthorpe, make sure you are in an aircraft that can get in and out! Pretty short runways there.
Always make sure that you remember to make the recommended allowances and add safety factors when doing performance calcs for grass strips.
It is commonplace to be requested to land to the left or right of the centreline to spread the wear - in fact the centreline is usually the bumpiest line! So be prepared for that. Keep the weight off the nosewheel as much as possible when landing and taking off.
tacpot is absolutely right - taxiways and runways can be very hard to see when you are on the ground, so be prepared to stop and ask if in doubt.
You should taxi a good deal more slowly on grass to prevent prop strikes and stone damage, and if there's a mixture of tarmac & grass, be extra careful when moving from one to the other - try to cross the join at 45 degrees if possible.
