I found out that my friend who crashed on Saturday was out for a while. I don't know how many concussions he's had, but it's a lot. They say he's been unpredictable and eratic on the bike lately which surprises me. Last time I rode with him I didn't see that, but he does move around a lot.
This guy raced in Munich in 1972, ffs. His skills were always very high and I have felt confident riding near him for more than 20 years.
