== Aerodrome Weather Reporting == 

 So, I fly out of Winsor, ON, Canada. I only hold a recreational permit, which means I'm not exactly a frequent flyer; just going out for fun every once in a while. 

 However, while checking the weather this date, I found this METAR; 
 METAR CYQG 161800Z CCA 29012KT 15SM BKN240 BKN270 08/M07 A2989 RMK CS3CI2 CONTRAILS SLP124=  

 For those that can't read these, here's a simple breakdown... 
 There's some unnecessary stuff for this perticular article, then in the remarks section (.. RMK CS3CI2 CONTRAILS SLP124) it mentions contrails in the area. Now, like I said, I don't fly much. But is there any reason a small operation airport like Windsor would need to declare contrails in the area? Anything above 3'000 feet over Windsor is Detroit airspace, so they would want to post this... right?
