I'm sorry to hear that your ride this afternoon was so stressful! It never ceases to amaze me just how selfish and inconsiderate people can be sometimes. I have encountered a lot of the same issues you list here, and can imagine that they are so much more frustrating when you are new to the sport and need to concentrate so much harder to safely navigate the obstacles they create. Despite your stressful experience, you sound like you have a good outlook on the experience - you certainly did get to practice your defensive riding techniques !

I really hope your next ride is far more pleasant and far less stressful. If not, be sure to tell us, and we'll arrange for a TE squad to come out and clear the path for you
