It was a late spring trip after a collaboration meeting in Oxford, measured events mimicking proton decay the topic, after jumping the channel Bill and I took into the Alps in a car, part of a five day tour, exploring villages, baguettes, and bris cheese cut and spread with our matching Swiss Armies, stopping overnight with each sunset where our Michelin map allowed, when deep into a long uphill road which we discovered as impassible, snow filling the span and blocking, yet melted, the wall being ten or more feet high, we retreated back down that long road in constant conversation.
