Colin, when I retired from Uncle Sam’s Canoe Club I swore I would never be cold or wet or both at the same time. Now I am planning on such a type of living after SHTF so lessons learned are being applied.
Only good thing about you and a hundred and seven of your close friends living/eating and working within 600 square feet is everyone smells the same after 2 weeks of living in your clothes! Hopefully you will find this out while at Ft Dix during maneuvers and not in Iraq!
Now that you have faced your fears and overcome the rest is downhill.
