AAFD was on the scene in just a couple of minutes. They were thorough, professional and their competence was reassuring. The ER kicked me loose a few hours later after determining nothing was broken. The bruise on my right leg hurts like hell, but otherwise I'm extremely lucky.
Many thanks to friends Dave Mumford and Craig Lindsey who stopped to lend support. Dave collected the bike parts and followed me to the hospital. Then stayed until Tivy and Taylor arrived to collect me.
The crew of AA Ambulance number 17 and the AAMC ER staff were wonderful.
