Christian,
You have a great adventure ahead of you.
That being said I went to Basic at Ft. Jackson and it sucks in the summertime. Heat, humidity off the chart, mosquitos big enough to fly off with your helmet, ticks from hell and grits with breakfast every day.
John, I will match Ft. Jackson for Ft. McClellan suck factor any day but then I went through basic in the worse recorded heat wave in 135 years. We lost 12 guys including a West Point cadet and it was like that all over the base. The fallout was so bad they sacked the base CG.
