Why not hand everyone a small rake, the size of a fly swatter, and apply the "oiled-sand greens protocol" to designated sand traps....no rakes on the course and allow the player to rake his lie.
Count me amongst those that think that the "no rakes" solution is anything but. Things weren't always better just because that's the way they used to be, or that's the way they do it at Pine Valley.
For my part, I try to return the rake to wherever that particular course puts them. Seems that in the US this is a big question. I recall an article in Golf Digest maybe 10 years ago discussing the topic, the argument for in, out, Stanford, or those pop-up things (which I agree get slimy, and sometimes the lids jam)
