Here's a good one. I have had bad knees for years, and have just recently started wearing a brace on my right knee that uses magnetic therapy. Don't know what kind of luck people have with these things, but it works great for me. Until I visit WDW.... Seems thet since the brace is on my right knee, and I carry my wallet with my Florida residents seasonal pass in my right pants pocket, the magnets are wiping the info from my ticket! I have had to replace my ticket 3 times in the last month and a half. On our last trip earlier in November, it happened again. So, when we go back in December, my first order of business will be to replace the ticket once again and start carrying it in my left pocket. Ever hear of such a thing? If you wear magnets anywhere on your person, it may happen to you.
