Bah, there are always going to be people who think your hobby is 'weird' or 'useless' or 'a waste of time'. Lord knows people wonder at most of my hobbies, including my enthusiasm for aviation.
I'm not a 'spotter', if we use the definition of tracking registrations etc., I just love watching airliners. It started when I was 4 or 5 years old, when my dad would take my brothers (7 and 9 years older than me) to the airport (Toronto) and I would tag along. I quickly developed the talent of being able to look up in the sky and announce, "47" or "DC-9", which wasn't a pastime shared with my girlfriends.
Today, I get to the airport early for flights so I can wander and admire. Twice a year I head to the airport for the sole purpose of watching the planes from the T1 parking lot. Gah!
They closed that parking lot. Anyone know where a good onsite spotting area at Pearson is now?
