I find now I own my own aircraft, I care a lot more about how I (and others) park it and leave it.
Phone Shobdon, ask if they have tie down spaces. Take some spare nylon rope and something to cut it with.
If no permanent tiedowns are available, take at least two spiral screw tiedown spikes, park on grass into the prevailing wind, lock the controls, chock the wheels and screw/rope it all down securely - there should be tiedown points on the wing of your a/c. You can get these spikes from pilot shops for about £20, though I've seen pretty good ones for £1 each in some bargain shops (advertised as dog tiedowns!). Or your club may lend you some if its their aircraft.
I usually set the prop horizontal. OK, the rest of the aircraft might get damaged, but maybe I'll be able to sell the prop afterwards!
Check the forecast for overnight wind conditions (direction/ strength) and secure accordingly (ie may need 3 or 4 tiedowns if its going to be a gusty night).
If leaving aircraft parked in the open for long periods, Bettaware market a car/caravan dehumidifier for £6.90 ish. Basically a tray with renewable silica gel in. Helps prevent condensation and thus wear and tear on the avionics.
Plus of course a decent tailormade canopy cover to stop the rain p*ss*ng ing in and the heat frying the insides....
