Made another pass this afternoon with the same results, although I did see some interesting vans; a nice StepVan and an Okanogan conversion Dodge highroof. Never heard of that brand but it looks pretty nice and even huger than mine.
I probably missed a few blocks in that area and there was one neighborhood that, while not gated, had lots of signs warning non-residents they'd better behave so I took that as an invitation to stay away. If the SM was in there, good riddance. Anyway, I'll probably give up at this point but will keep an eye out for the orange van in motion. That area is outside my normal orbit so spotting the Sportsmobile will be dumb luck from here on out.
