My hometown has received a beam too. Such an honor.
There were 2 firemen in town that honored the firemen lost in the Towers by walking up and down the stairs in the Sr. Highrise (lol 4 stories) until it equaled the total number of flights in the Towers in full gear, carrying 50ft of hoses and other equitment each. Just like those lost in the Towers would have been doing.
You have all rights to be proud of your daughters and husband. OOOORAH!!
