I don't know if this is really a danger, but a group of us girls went to the American Bar in Kilronan and felt really uncomfortable there. Some of the men (and there were only men in it) looked like bikers, which we found odd for Inishmore. We only stayed for a few minutes and then left because we were receiving unwanted attention, and not in the nice friendly way. Later, the woman who ran our hostel said that a lot of female travelers feel the same way about the place.
I guess the moral of this story is: if you feel uncomfortable then leave.
It seemed a good idea at the time
If you visit the Aran islands, it is obviously a temptation to buy an Aran sweater.
The only problem with this plan (apart from the cost) is that only two types of people ever look good in such a garment.
The first is pencil-thin female fashion models, who you just know still have a great shape under the lbs of wool and cableing and the other is Ernest Hemingway. All other wearers look suspiciously like a sack of spuds with a fashion by-pass.
