I emigrated to Western Washington State in 1968 after 18 months riding test bikes for N-V and riding generally for the previous 10 years in the UK. I started out on a 150 Vespa (because Mom "didn't like motorbikes") and graduated to a 250cc Ariel Leader (chosen because it didn't look like a motorbike even though it was one). Final ride before getting married and becoming a parent was a 1958 BSA A7. For a short time the BSA had a single-seat sports sidecar on it, but that ended when I was sneaking thorugh traffic with fiancee in the chair. I forgot it was there and ran her into the back of a bus! Low enough speed, didn't even damage the paint!
For about 9 months, I rode the prototype Commandos on endurance testing, then switched over to the AJS Stormer program. I was a dead loss as an M-X rider, so I only rode the Stormers on test.
I took one look at the driving habits of Washingtonians, after we got here, and decided I didn't want my wife to meet a State Trooper at the door. With the demise of the "big barges" (Chevy Impalas, Mercury Colony Parks, etc.) things are a bit better than back then. Unfortunately, at just on the wrong side of 70, I don't think I'm up to the challenge any more.
