So with my increased awareness, Last evening I purposely rode over to our MUP path -known as the greenbelt. I made it about two miles before hopping off and getting back on the street. It was "rush hour" and between other cyclist riding way to fast for the congestion (IMO) and many walkers and families on bikes I was totally stressed out :)
I found myself not calling out on your left (heeding the advice of many of you) but instead just slowing way down and moving as far left as possible and saying hello or good evening, instead - thus with the congestion most areas I would have been faster as a walker.
So I concur, whenever possible, MUP riding is for laid back noodle riding. If I needed, I would certainly use for a commute ride and just recognize I shouldn't plan on getting anywhere fast and I will certainly not plan a weekend ride at a quick pace. Meanwhile when I do come upon slower walkers or riders out and about I promise to do my best to make myself known.
