Awesome weather today. The TV said it was 60 degrees when I left earlier than usual to get a nice long Friday morning ride before work.
Usually I carry a yogurt and a hard-boiled egg (and some other stuff - wallet, keys, etc.) in a "soft" handlebar bag on my road bike. It's a bag that straps to the handlebars and hangs pretty loosely, unlike the nicer, larger ones I've seen pictures of that firmly attach to the bar with metal or plastic clamps.
Today, however, I used a different bag to carry my stuff and firmly strapped it it to the recently installed front rack on my rigid mountain bike and rode gravel most of the way to work, including one long, fast, bumpy downhill shortcut that I always avoid on my road bike.
When I got to work today, the hard-boiled egg had pretty much peeled itself and the yogurt had exploded. Eww.
Lesson learned: breakfast needs suspension, even if the suspension is the merely the gentle swaying of a handlebar bag.
