I like the bell which can be heard far enough back that the reaction comes before I get there. I hated having to yell, get 0 reaction and then yell louder. Usually I stay off the MUP as the tree roots are ridiculous and even though the MUP is super busy
and used as transportation the city/county has no interest in maintaining it. If I want to mountain bike I head for the trails. Sorry for the rant.
