Hi, Does "a straight shot 100 miles" mean "100 miles in a crow line"? Here is the context of the expression: - This border, which is established by the Gadsden Purchase, this is a straight shot 100 miles to the Rio Grande. - It's amazing. - It's a pretty straight shot and then this flatland goes a long way. (Quoted from a documentary TV series The Desert Speaks) Thanks very much!
