I googled your locations and Pearson wasn't probably in the way for you?! I am wondering how the radar system or airplanes descending or taking off might effect this as one of the location for me has to point right through the airport.
I will have to do a preliminary binocular check to see how far I can see. I might have to first map a few land marks to even come close to know where to point the binoculars.
