Bulgaria 2009 - one of the best finds -very random. Driving back to hotel and spotted two folks by side of road. Drove past, started thinking - two people by side of road with what looked like snake stick - stopped and did U-turn. Stopped and out pilled 4 ecologists - 2 birders, local guide and bat specialist. Found 2 Germans not with a snake but a mole rat they saw running accross the road. Very nocuturnal, very enexpected and uterly brilliant.
