Played Blackstone National Friday morning and am happy to report they seem to have recovered from their problems suffered during the drought of last year, course is in nice condition. Of course now they have some problems due to all the rain this month, but a lot of that is mainly erosion on cart paths and some other areas not all that critical to the course itself.
The last round I played where the course wasn't squishy was in June. With all the rain we have had so far this July, courses are very wet, and play longer too.
