I could easily have died tonight - and I didn't know it for 15 minutes.
I got a new bike today, which makes me deliriously happy, and will be the subject of another thread. After doing lots of riding, I went to visit a friend, show her the bike, pick blackberries, and hang out for a while. It was later than I planned when I left, and drizzling a bit; it'd been raining harder earlier. My phone rang several times on the way home, and when I got home - it was my friend.
Three minutes after I left, a car came speeding down the road, probably doing ~60 mph on a road made for 30. It hit a tree. The driver is dead. Fortunately there were no passengers. He was going the same way, and in the same one lane as me. If I'd left just a moment later, I might have joined him. She says the road is full of police and fire trucks.
My last bike has a dead battery in the rear light, which I hadn't replaced yet... The new bike has front and rear lights - the rear one takes rechargeable batteries instead of proprietary, hard to find ones. If I'd left a moment later, a back light would have been my only hope, and not much hope against someone who hit a tree.
Be careful out there, check your lights, and stay aware of what's going on around you.
