I don't think I'd ever want to play Saunton in May or June. My understanding is that Saunton are incredibly restricted with what they can do to the rough and that it is just soul destroying, ball gobbling crap at times. Reading between the lines on their website, I think Saunton would like to cut it back quite a bit more than they can:
"Saunton Golf Course is situated on Braunton Burrows, a sand dune system which is the largest in England and vitally important for its plants and animals. In recognition of this the Burrows, and hence Saunton Golf Course, have been designated as an Area of Outstanding Natural Beauty, a Site of Special Scientific Interest (SSSI), a Special Area of Conservation (SAC) and a Unesco Biosphere Reserve.
The effect of this is that Saunton has to obtain consent from English Nature whenever we wish to carry out any significant works on the courses, which could be in danger of damaging the Burrows.We have had to agree a Course Management Plan with English Nature, which dictates exactly how we manage the land."
I've only been there in September and October and the rough was fine, as I imagine it is from late August to early April most years.
