I love the concept of the challenge coin. Not having been in the military this is a new concept to me, but one I see a good deal of merit in. I received my 6 last week. Damn, they're heavier and bigger than I thought! My thought was to give one to each family member, attached to a chain that they would wear around the neck inside their clothing. Should any situation arise that help was needed, the coin could be produced outside the clothing to let me, or any TSP member know help was needed, without the BG knowing anything was up. No big display of "help needed", just a sign to let it be known the situation was not as it seemed. I'm still going to try this, but have also added the fact that I can wear it outside my clothing in public, after notifying the family. This would serve two purposes, 1. TSP members would know me as one of them and 2. Non TSP members would ask about it, giving me the opportunity to advance the cause. I carry one in my pocket too. I enjoy taking it out and spinning it on the bar, it's so heavy that it takes forever to stop and has quite a unique sound while doing so and always produces a lot of interesting responses. There is a helluva lot of people that think like us but think they are alone. I've been pleasantly surprised and as of yet had no negative responses. So, If you see a redneck cowboy, with a TSP challenge coin around the neck at your local IHOP, coffee bar, real bar, or AG store, come say hi, but if it's out on the side of the road, please ask if assistance is needed.
