We have some nice MUT's here which once you get through all the goose sh*t are pretty nice not too many people. There are times when a group of 3 or 4 are walking (side by side) towards you oblivious to the biker traveling 20mph hello! My favorite is passing someone yelling "on your left" and watching as they try to figure out which side is their left, "no your other left".
But if you do that too many times, no one will come to your aid when there really are killer bees after you.
Then where would you be?
Hmmm, on the big ring pushing over the peds, hopefully the bees will go for the fallen.
Other cyclists I'll spare the push...unless side by side, in my way......
those I would ride off the trail for, and say nothing about the bees around the bend.
How about a small plastic megaphone and a radio hooked up together?
90 decible burst of Halen will do anyone.
