In 2003 I was there in early June and the flowers were amazing. I went back this June and was dissappointed by the lack of flowers. I see you were there in late August and the flowers were spectacular again. I guess you just have to get lucky with your timing.
"All men dream, but not equally. Those who dream by night, in the dusty recesses of their minds, awake in the day to find that it was vanity. But the dreamers of the day are dangerous men, for they may act their dreams with open eyes to make it reality."
