I was considering purchasing some magnets. The cost is relatively inexpensive as long as you buy in bulk. They are business card sized or maybe a little larger but are personalized. The one I really like would have 2 photos (of landmarks from my city), the saying "Exploring the world, one cache at a time" , my code name and my hometown. Does this sound like something people would want to take with them? The magnets are vinal so they shouldn't have moisture issues either. Please let me know what you think before I purchase them. Thanks!
