just a follow up on the beach umbrella... extremely hot today at the Ruskin match... the umbrella was a tremendous asset to keep you out of the direct sunlight... I freeze a couple of 1/2 liter bottles solid and chill 4 others in the soft side cooler... drinking a sip of cold water fairly frequently really helps me with the match heat....only needed 2 liters for the 3 hour match.... I fore see an 18v Ridgid cooling fan in my future... it can be used during tropical storm season also
a tip to determine if you are dehydrated.... pinch your fingernail until it turns white, release, and the see how long it takes for the capillary refill to return color to the nail...longer than a couple of seconds, and you might want to drink some fluids....
