I was at Deal three days ago. In the 15 years I've been visiting there I've never seen remotely anything as bad as what I saw. Now, on Thursday they received some rain and Sunningdale where I played Friday was also very wet, but still the damage was clear. Standing water in bunkers, tons of areas that were green under repair etc. The greens were uber slow and being protected (although putted true). The course played like a wet marshy meadowland rather than a links. It was quite sad, I know the greenskeeper there is respected and doing his best, this is mother nature not anything else. FWIW, I hit some shots in the heather at Sunningdale New and when I found them I was in large casual water puddles (in the heather). While I didn't see damage at Sunningdale, it didn't play like a well drained heathland course either although Thursday's rains were heavy.
Lets hope for a dry summer.
