When I am Conductor (as I was at Fall Festival and Evening Moonlight), during the ride segment from Alna Center to Sheepscot, I always invite all passengers...
"If you like what we do at the WW&F, please like us on Facebook, Follow us on Twitter and other social media platforms. And, please, write nice things about us on the Internet on places like Yelp and TripAdvisor. This is how YOU can share the story of the treasure of a railroad we have in the Sheepscot Valley, help us to rebuild Maine history, and keep alive the railroad with Big Dreams and Little Wheels."
(I use "Big Dreams and Little Wheels" as a tag line during my standard history talks during the trip and TOM layover. Sometimes I will also reference to keep alive the dream of the little boy or girl inside of us - calling back to the story of Harry, etc.)
I know that we have gotten more than a few reviews thanks to this personal invitation.
