I just received this from our JPA President, Tom Dente: 

Hi Jane,
Our oldest son, Tom, ran the Boston Marathon on Monday finishing a little after 2 PM.  Following running the marathon runners drink fluids and eat some fruit and food products in a tent at the finish line. When they finished this they go to the bag area also at the finish to retrieve their belongings, (before the race your belongings, wallet, cell phone, clothes, etc.are put in a provided bag with your name on it). The explosions began just as Tom had gotten his bag he was about 50 - 100 feet from the explosions. He was shaken but not injured.  Normally, we would all watch the race from Boston College then after Tom runs by his wife, Liz, and children (our Grandchildren) would go toward the finish line to meet him and watch other runners finish. Camilla and I would head to Connecticut to beat the crowd. This time however, Liz, our grandchildren, and Camilla and I were not at the race as we have in the past because of the kids sports and activities schedules at home. If his wife and children had been at the race they likely would have been in harms way at the finish line. God works in strange ways!
Tom

 We were concerned that Tom's son might be running in that race, and are so relieved he was not hurt and that the family was not present.  The whole family must be shaken by this and forever thankful they apparently all had angels on their shoulders.  Thank you, Tom, for letting us know.
