Panty trail for you to find! SeXStoRY

I'm going on a road trip tomorrow, diagonally across the UK. My wife always slips a pair or two of her panties into my bags for me to find when I reach my accommodation, but this time I'm going to drop off some of my panty 'stash' that I've accumulated over the years at various way-points en-route. My thoughts on the best way of doing this are to visit the loo in as many motorway services/filling stations as possible and leave pairs of panties hanging on the coat hook behind the door. The thought of a score or more of men wanking into the underwear that has been in close contact with the most intimate part of my wife's anatomy is a real erotic fantasy for me. I often fantasise about parking up in a remote lay-by somewhere, and 'accidentally' allowing another male motorist to catch a glimpse of a bag full of my undies stash, perhaps in the boot of my car, striking up a casual conversation with them, the undies coming under discussion, comparing thoughts what men like to do with them, - would they like to try some, should we sit in the car together for more privacy, mmmmmm lovely cock - looks so good stretching my wife's panties like that - big purple bell-end with the transparent material pulled so taut over it, glistening pre-cum just oozing through... - do they need a hand with that? etc, etc.... Does anyone have any suggestions of a good place to drop panties, where furtive panty searchers might cast a glance if the hope of finding a frilly fantasy come true?
