Sorrry to hear about the conditions in Philly and the rest of the NE.
St. Louis has got to be one of the most difficult regions to grow grass; very high temps/humidity in the summer and rather cold winters. My own course, Westwood, is one of the few remaining clubs with Bermuda fairways (Westwood Bermuda, to be exact). Our greens are Bent, as are the aprons surrounding many of the greens and they are in spectacular shape. Our fairways have been another story, although we have an outstanding Super that's been managing quite well, considering. We had the St. Louis District Championship last weekend and the course was in great shape (thank goodness for lots of sod!).
Most courses in the area have converted to Zoysia from Bermuda at one time or another, with rather mixed results.
We are experimenting with Riviera Bermuda (Oklahoma State U.) with the hope that it will be used with the Westwood Bermuda and give us a more consistent coverage. During the Spring, we rely on overseeding with Rye to fill in the multiple open patches on the fairways and that tends to disappear with the heat of the summer.
I've been to Philly twice this summer to play (great conditions) and will be there again next month...
hopefully Mother Nature will begin to cooperate. Best of luck to all out there!
