I had planned to meet a group of old school chums at Lincoln Station, a commercial area in Lincoln, a town next door to Waltham. When I got there, I found that they were all stoned. I wondered, how’s that possible? Frankly, I was embarrassed. But I dutifully took their pictures (below), made my excuses and headed home, hoping that was the last of it, that I'd hear nothing more about it.
