For July/August 2021, two interesting air shows are scheduled in Canada and Alaska. On 31 July and 1 August 2021, the Arctic Lightning Air Show is scheduled to take place at Eielson AFB in Alaska. One week later, 6 to 8 August 2021, the Abbotsford International Airshow will take place at Abbotsford, BC in Canada.
If we consider Alaska, British Columbia, Washington (state), Oregon and Idaho, we could make a very interesting tour. Bases that come to mind; CFB Comox, NAS Whidbey Island, McChord AFB, Portland, Boise, the Boeing Everett Factory, etc.
