I have a hill on my favorite route that is pretty steep and if you get a tailwind, you can get up to 45mph. I had a tailwind once, going over 40mph and I saw something in the bike lane. As I got closer, I realized it was a railroad tie that probably fell off a truck. I didn't slow down because I was just going to go around it. As I approached the railroad tie and ready to go around it, a truck came to my side blocking my path. It was too late to slow down, so I bunny hopped it going 40mph. My front tire cleared it, but my back tire hit the top and I hit hard but landed it. My heart was racing big time after that. Every time I'm going over 40 mph, I am looking for any rock, sand, or any obstacle that is going to send me over my handlebars.
