A bounce off the thread listings of people who have digsites they absolutely dread, and of course, I have my own demons, but that doesn't stop me from grinning when I get some of my favorite digsites. This can also extend to the little things in Archaeology that keep you going, such as a Triple-Survey in one spot.
One of my favorite digsites by far has to be the really tiny circle one in STV, Balia'mah Ruins or the Ruins of Aboraz (also in STV);
And the little things that keep me going has to be the small chances I get to revel in the little "Double-survey" spots where you survey, get your fragments, survey again and another spawns right there. Good times.
