Watching News of the World on Netflix last night, I spotted (in a film with an interesting conceit), one of the great cowboy cliches. When you're being pursued across a featureless landscape, you always manage to reach a rocky outcrop before the baddies catch up. Leave your horses somewhere and take cover behind a boulder. If you're any good as a goody, you should be able to pick off your pursuers one by one, even if they taunt you with the hopelessness of your position. Of course this made me concerned for Shanahan, Shorty Andrews and Slug Willard, the fearless cowpokes of the Circle N as recorded in Flann O'Brien's At Swim Two Birds. Are there enough hills that meet the requirements within the county of Dublin? Would Howth Head suffice? They should be prepared. Even Butch Cassidy and the Sundance Kid had to resort to a rocky hideout.
