Tinker I'm seeing the same thing at several courses we play. I can think of one city owned course
(also on the second hole, BTW....a par three though) where a huge bunker you used to have to avoid at all cost is
now grass and weeds. The many other bunkers on that course are maintained, but just barely. They haven't seen
new sand in a few years, so if the greens crew or playing customers don't rake them they're really tough to play out of. On another course, I can think of at least 2-3 former fairway bunkers that are now just grass. In our travel
group we have agreed to adopt a "rake and roll" rule if you find your ball in a bunker, due to little-to-no maintenance.
OTOH, the course I consider my "home" course was just taken over by new owners this year, and one of the first things they did was install new white sand in all the bunkers. I'm not a particularly good bunker player, but I'll have little chance of ever improving if bunkers and/or bunker maintenance at most of the other courses I play continues to be neglected.
