On the Mohawk Trail, that stretch of Route 2 from Greenfield to North Adams, someone’s secret work emerges in (Just-?) spring. This past May, a few daffodils appeared on the roadside in a secluded but sunny slope on the south facing hill above Shelburne Falls. Soon, another bunch appeared a bit further down the road. And then a spray on the other side of the road. Within a week or two, daffodils, narcissus and jonquils lined the highway from Greenfield all the way to the entrance to the state forest just past the Zoar River.
