OMG I'm laughing, at least it's good to know you're not alone!
Cracked up at the Hansel and Gretel idea, we could put bread crumbs down but they'd probably get eaten by birds so we'd be back to square one....
The photographing of the car is a good one, never thought of it, can never ever remember where mine is, the direction I came in to the parking lot, left section or right...
Don't know if anyone else does this but when I have an appt the next day, that night that's all I can think of...don't forget...and hardly get any rest which is of no help...oh boy...
