Oh, that's brilliant, MrsB!
I should have thought about that. I never go into the countryside without my trusted rock hammer, be it to fend off wild dogs (only happened once, fortunately) or to collect rocks. The whole country is full of geologists anyway, so I'd guess such weired stops aren't totally uncommon. The roads will most likely be endless and straight but it should work out if the car is parked a bit away, and once summer is over. I don't want to get barbecued out in the desert
My target is to find each and every cache in that small country while I'm there. It should be doable with some preparation as there are only 130 or so in total.
And related to that: I so often take taxis from airports and always get annoyed if the travel bug hotel is just out of walking distance and the taxi is passing it, and there's no cache near my hotel. Maybe I for once should ask a driver to stop nearby, also good preparations assumed.
