Yeah, that one is kinda close, but there is room between them. That's all the room I had to work with, and they'll still fill in nicely.
The real point is that strips with a bit of room between them is better than a single large 18" square that a lot of even better players leave behind. Unfortunately the bomb crater scenario (like where I'm standing in my pic) is a lot more common than either.
We have 2x4's dividing each hitting station, with spikes holding them in place, I find that after awhile, if the grounds crew hasn't moved the dividers in a couple days, I end up moving the dividers a foot or two in order to use some decent grass. I shouldn't have to do that, but it's just amazing how many people think just like the OP. The majority of golfers, unfortunately.
