Glad that you did not get hurt worse - sorry that you took a spill. We ride the 2 mile loop in a park near our house every now and then and there are always people, kids, skaters, elderly, and the kamikaze squirrels to contend with. Plus one jerk who rides extremely fast through there with headphones on. I usually start braking when I yell out “On your left” just in case they react poorly. I especially have had kids get very confused and sometimes they will turn directly into my path. I am currently nursing a road rash elbow - I was stopped at stop sign and leaned too far to the right and literally fell off my bike last weekend. At least you had a legitimate reason for your spill - I was just careless. Hugs and prayers for quick recovery for you!
