I finally learned to fly
Flying was my childhood dream, and during the COVID lockdown I finally did something about it. It’s purely a hobby: weekends and vacations, nothing more. And I’m grateful I get to do it at all. So far it has taken me out to Orcas and Friday Harbor, and as far as Oregon, California, Nevada and Idaho. Plenty of map left.
