More than two dozen families in Nashua won't have to worry about what's for dinner or under the tree on Christmas, thanks to an annual effort from police and school officials in the city.The families are being treated to either a ham or turkey dinner with all the fixings, and some presents, too."It really makes Santa feel good and get me in the mood for the big trip," a man portraying Santa Claus for the event said. With police vehicles doing double duty as Santa's reindeer and sleigh, the first stop Wednesday morning was a preschool. Then, it was on to make deliveries all over the city.Nashua's police chief said the event is his favorite day of the year."Just seeing how happy they are when you show up and you know you get a bag full of toys and you get Christmas dinner and just seeing the smile on their faces," Chief Kevin Rourke, of the Nashua Police Department, said.This is the ninth year for the program, which started out as a partnership between Nashua SWAT officers and the Nashua Police Athletic League.Now, the initiative involves much more of the community, including the work with the school district to help identify families in need.When the program first started, organizers were able to help eight families. This year, thanks to increasing donations, they are able to help many more families in need. "Bigger and bigger and bigger. So that's partly the demand, but partly just good-hearted folks at the police department and Nashua PAL to do more," Shaun Nelson, of the Nashua PAL, said.Despite the generosity, there is still a feeling among some that more needs to be done."It makes me ever mindful that there are many in need this time of year and all year, and it's a special time and we try to accommodate those that we can," the man portraying Santa Claus for the event said. "Unfortunately, I don't think we get everybody."
