With all the complaints about the heat and humidity at the Bloomsburg Rally..maybe try attending this event and learn how they "deal with it"..
..with the daytime temps hovering around 110f+ and night time temps around 50f.
I regularly talk to a person who volunteers as a EMT just about every year and can't enough of this event. Yes it's not your average event and not for everyone but I'm looking at it as learning survival/adapting techniques for future rally considerations.
..just my 2 1/2 cents..
