Qa'lat al Marqab
I really tried hard to not pay the entrance fee at this crusader castle, climbing through a gap in the wall and trying my best to not be seen. Of course, I was caught at the very end while I was leaving (having missed parts of the castle in order to not be seen). The guy came up on a motorcycle asking why I climbed in through the wall and blah blah... I offered to pay for a ticket and after a moment's hesitation he offered to charge me 30% less in exchange for him not issuing a ticket (in other words, a bribe). I said yes. Nice castle, eh?
