Caption: SEASON'S FIRST--The first snowfall of the season gave a nice patina to communities in northern Ardebil and East Azerbaijan provinces last week. It was enough to get out the snow shovel and enough for the kids to have a snowball fight. It was also enough to close schools in Ardebil for two days. But north of the border in Armenia, it was much heavier--a veritable blizzard. A rescue team had to be dispatched to the aid of a bus carrying a group of Iranian visitors. The bus, with 27 passengers, was trying to return to Iran when it got stuck for 10 hours.
