I was in Switzerland and Costa Rica earlier this year and

DID NOT SEE ONE lingering con/chem trail in either country.

I pay attention to this stuff since my trip to the Grand Canyon two years ago. On that trip the days started off clear and then as far as eye could see, in any direction, trails took over the entire sky and by lunch it was hazy - every day.

Now I pay attention.
