Well, luckily the Home Depot is right next door to the Office Max! I bought 2 "make-your-own-luggage-tags" that you can self laminate (just about anything). I put the LGMH back to back and just stuck them there. I would have put my board name on there, but I didn't think anyone would know who I was anyway!
I also made some "calling card" types to hand out. But, I felt a little silly, so I never used them. They had my board name on them, though. I wish other DISers had them when I went in September. Many people came up to me, we chatted... then I forgot their board names! So, maybe I will use them after all!
I handed my DD her LGMH a couple of weeks ago. I said "you need to put this on your park backpack". She just looked at me like "OK....".

And then she signed up on the DIS!
