Hence the [sass]. It's a thing on some forums to bracket or change color of text when making a funny.
I gave up on that fast greenway stuff long ago. Too many people to hurt. I just use them once in a while to link up sides of town. I've figured out how to navigate lots of neighborhoods by memory and just use the greenway for a 1/4 mile or so to cross major roads and such.
Since it isn't really safe on our greenways to blast along (way too many sharp/blind curves), it's faster for me to link up the neighborhoods and maintain more pace that way.
I can see your point though if you're on one of those 30 mile long midwestern greenways where there isn't a turn for 10 miles at a time. Around here, ours all follow winding creeks and rivers. So you only go straight for maybe a half minute at most at a time.
