This is cache is located north of YYC and from here you will see flights operating from the parallel runways. Either arriving or departing depending on the winds.
"YYC consists of two north/south parallel runways with two intersecting runways. The parallel runways are referred to as 17R-35L (the west runway) and 17L-35R (the east runway). The diagonal runway 11-29 is used as a ‘crosswind runway,’ meaning it is used in extreme wind conditions that prohibit parallel runway use, and is also a preferential runway for night-time arrivals. The final runway, 08-26, is almost exclusively used by light aircraft and the general aviation sector."
You are looking for a small tube with just room for a log so please BYOP.
