i was in barcelona and was catching a bus to the airport at am. there were other people waiting. a car came out of nowhere and the guy said he would take all of us to the airport for euro. it did not even look like a cab. i felt sketchy about it.
thank goodness it all worked out! it sounds like you took a bunch of smart precautions!
we did. this british chick convinced me it was worth the risk. the chinese tourist couple just went along with it. i refused to put my backpack in the trunk and rode up front with it in case i needed to tuck and roll hah. had my phone out with the gps to make sure he was actually going to the airport. it all ended up being fine...aside from the speeding.
