just a brutal day in dallas today. 94 degrees and super humid. the heat index was 107. 1st couple of holes i was pumped up. by the turn i was spent. I drank a lot of water, pour cold water on top of my head. but nothing helped. around 16th i was ready to get off the course. any secrets on how to remain focus when the weather is like this? i think im just going to have to start booking 6-7AM tee times.
