Work being done on the greens

As I type it is snowing ... and called for 15 cm so Friday opening looks doubtful ... work is being done at the course and the greens have been aerrated.

Question: Do I Get Relief from Aeration Holes on the Green?

Answer: Most golf courses, at least once a year, aerify their greens. Aerification, or aeration, is the process of punching small holes in the green; actually, small "cores" of turf and sod are cut and removed from the green (read more about aerification and its purposes here), which leaves holes.
It usually takes the green a couple weeks to heal following aerification. During those couple weeks - and especially in the several days immediately following aerification - the aeration holes are quite a nuisance. They can certainly affect a putt, especially if your ball happens to come to rest right on top of one.

But does that mean a golfer whose ball is affected by aeration holes is entitled to free relief?

The answer is a qualified no, with an exception possibly provided through a local rule.
