Your fear of dogs is completely understandable. I've not even been attacked, and they scare me. Remember that more often then not, you will just be chased. Remember to yell at them to go home or get back. Stop your bike if you must until they retreat. You can do this!!! Just keep your eyes peeled. Have fun on Saturday. I haven't done that one before. Sadly, I haven't done a CIBA ride since last July.
Here's another tip: keep the maps from the rides and note what color/shape Dan Henry's it used. Then you can go back and do the route on your own if you like it.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
