BTW, when we went the first time, the tunnel had a lot more windows and much brighter. Now they basically closed 50% if not more of the openings - the view is greatly diminished.
Finally, dont use Asprin - should bring painkillers that do not contain Asprin. Extrastrength Tylenol is a stable in our firstaid kit. I actually wonder if you guys carry a proper firstaid kit? One that contains sterile gauge, pad, antibiotic oinment, scissors, rubberband for stopping bleeding, basic medication, etc etc ?
