Because we lived overseas for many tours in the past 30+ yrs and with two grown boys, we've collected about 50 pcs, small, medium, large! I used to be a carry-on bag freak, always buying the 'next perfect bag' each business trip.

Now we're down to about 30+, about 10 in a cedar closet for storing seasonal clothing, the other 20 up in the attic (anyone need an extra bag, pm?).

When my wife travels, she has a minimum of three large check-in bags - two packed with gifts/household goodies, etc. for family members. I, on the other hand use a 22" roller/carry on, a large northface backpack and tumi computer bag!
