Strange how those little yellow magnets always get debated in posts like these. Still though somewhere in the back of my mind, I like to think that when people see one of them on the back of a vehicle, that perhaps they think of, or say a prayer for someone like my son. Then again I'm biased and think of my son every minute of every day and don't need the magnets as a reminder.
BTW, NCB's suggestion to send things to the troops is a good one. Hygiene products are just as welcomed by these men and women as snacks and candy. We send DVDs when we send packages. After the movies are watched, they get passed around from Marine to soldier to Marine and back again until it is unwatchable.
http://marineparents.com/ always has suggestions on what to send as well as the best way to send it.
