If I was forced to pick just 1 thing, then it would be DRAINAGE to make it more playable for more of the year
If I had more choices, it would be
2) Some Level tee boxes, think theyve buried a couple of elephants under some.....
3) The same sand in all the bunkers, reckon we got 2 or 3 different types, and the same amount in each would be a Bonus too
Level teeing ground comes up a lot.
Not surprising as teeing area tends to shift due to constant cutting.
