I was in Montreal last August for my niece's wedding. Besides spending time with friends and family (and even eating a snail), I also did sight seeing along a railroad and loitering in deserted parking lots behind buildings. The quest of my latter activities was the European land snail Cepaea nemoralis.
The results of my vacation research recently got published in the open access journal Check List. You may download a copy of it from here.
