The most frustrating course I have played was Warren golf club in Essex , to be fair the day I played it , it was raining heavy but there were cross overs that made the course take so long to complete it was a nightmare.
The round took five hours !!
I have since heard that there have been some improvements to the course so hopefully the layout is different now, and on the plus side they were a very friendly bunch of people and gave us a free game voucher.
