I’d already made plans to attend this Saturday’s sneak peek of the St. Johns Museum but I only just noticed thanks to St. Johns Boosters that there’s going to be a presentation by Dan Haneckow on The Great Light Way, the series of illuminated archways that once adorned more than several intersections along SW Third in downtown Portland and if you followed me at all during my Portland Communique days, you already know that I’m so here for it.
