I was up there in june 1988 in the u.s. airforce at edmonton for a weekend to the north american mall for a couple of days, but was at cold lake air base for two weeks for a joint exercise it was located about 100 miles north of edmonton . i remember the temps in june at the base was around low 70s and the day we left was in the 40s . my field jacket was packed away all i had on was a short sleeve .
