Sneakylong slow golfers
That's a 'grouping' with many different definitions though.
If they play in 4 hrs., imo, that's not slow as it is still under guidelines of almost every course. I've been behind groups that certainly appeared to be beginners, spraying shots everywhere and no way broke 100 or even 120. Slow play??....I did not play through and was done in under 4 hrs.. Yes, I waited a lot but was in no hurry.
Slow play is the group that has 4 really good golfers that are shooting in the 70's. And takes 4-4+ hrs.; walking or riding makes no diff!!
When we have a group, 4some, playing, I keep watch behind us only. And keep us ahead of anyone behind, unless a single/2some, then I will tell the group to let them play through. Even though we are not 'behind'.
I've played, using cart, in under 2 hrs. many times. And kicked myself in the ass for doing so, even while scoring great.
