Just before Christmas I spent an hour in a ditch with a broken hip after cycling into a a sheep (I'm from New Zealand and they crowd all our roads and are a frequent hazard). I was in a rural location so I had to spend quite a bit of time on the phone with the emergency dispatcher, while in a not insignificant amount of pain, trying to describe my location in relation to various landmarks. The dispatcher was in a different part of the country and was unfamiliar with local landmarks so this was very frustrating. I found out later that there is a increased probability of complications (avascular necrosis) if there is a delay having surgery following this type of injury (I'll know in a few month if I need to go back for a hip replacement). Not sure if an extra 10 - 15 minutes it took to get a ambo to me would have helped, but I'd prefer the odds my way where possible! My parents were confused by how I wasn't able to send the dispatcher my exactly location over the phone.
