I realized this weekend, that when I first began my TB journey, I went in with all the stuff that I HAD to carry on business trips in my carry on - attempting to find the perfect bag for it all. I tried the Western Flyer and found it too small. (I tried many bags, but that story has already been chronicled in another thread).
Today, I can carry my entire travel work carry contingent in a co-pilot. Quite a change Oddly, whatever it was I used to carry - I don't miss.
(it did help when I finally got the company to downsize me from the enormous laptop of evil to a small model..., but even before that, I had moved down to a Pilot...)
I got my daughter a WF today (and a TriStar, she is trying to decide which is better) and she wanted help packing. She had what appeared to be a full WF, and a pile of stuff she couldn't fit in it. 10 minutes later she said "you are creepy", when I asked why, she said "you took a full bag, a pile of sweat pants, 3 jackets, 2 swimsuits and a #2 stuff sack full of socks, and and made them disappear into the bag"
Ahh, the magic of the TARDIS bags...
