Well my latest injury (that oddly enough didn't involve whipped branches or rose bushes) was not actually while caching but because I cache. I recently visited my doctor who suggested that I get a tetanus shot since I geocache and am known for being a bit of a clutz, lots of rusty old things out there you know. A few days later a different doctor without reading my file to see that I'd just gotten a tetanus shot prescribed a medication that was counter indicated for people with recent vaccinations of any kind. Wouldn't you guess it I landed in the hospital with heart problems, was scary because wouldn't a permanent heart problem just ruin my summer. Thankfully it didn't slow me down for long though was out caching two days later (would have gone out the next day but the weather was lousy, and I had friends threatening my life if I did)
