Hi and welcome to DPF! For me, I was certain that I would not get into pin collecting/trading. Then, during Star Wars Weekends this year, I picked up the annual passholder SWW pin and the Mickey in an X-Wing pin, and insisted that those would be the only two pins I'd get, as I'm a huge Star Wars fan. I put the pins on the strap of my camera bag and figured that would be the end of it. Then the Olaf "chillin'" postcard pin came out, and I just had to get it. But it sat too high on my camera bag's strap, so the back of it was kind of digging into my lower ribs, so I decided to get a lanyard. Well, the lanyard looked too empty, so I decided to get a couple of more pins, and well... here I am LOL! I've found the pins to be a great conversation starter with other guests as well as CM's, and I've quickly become addicted to pins. I seriously have to make a decision on what series, movies or characters I want to stick too soon, though, as I'm kind of all over the place in what I've been buying so far. It's both a blessing and a curse living so close to WDW and being a passholder, as I love going to the parks every weekend, but now I can't seem to leave without picking up a couple of new pins each week!
Anyhow, welcome to a very addictive hobby, and a very friendly, helpful forum!
