Please don’t cancel this event! I’ll bet your sensing a dropoff in enthusiasm that is only temporary. Once the date nears, folks will be looking for ways to commemmorate 9/11. For myself, whether there’s something “organized” or not, I plan on being on a mountaintop that day.
I’d recommend that in mid-July or mid-August you approach The Associated Press in Concord and the Union-Leader in Manchester to let them know what’s going on. A little advance coverage might help renew enthusiasm for the event.
