I will second the commercial oil distributor... Ours is in the next
town, 15 miles away... He has Shell and Phillips aircraft oils in
stock... He delivers to the airport at no extra charge... I just leave
the check on the table in the hangar... He drops the oil, takes the
check, leaves a receipt, and locks the door on the way out... I've
been hinting at his doing a bit of polishing on the wings also, but he
seems a bit deaf on that one...

Check the tractor store (farmer stuff) for landing lights... Other
expendables will probably be found at Wally world, etc...

cheers ... denny
