I know there is a lot of us who carry water bottles into security to fill.

1) What bottle or bladder do you carry?
2) Where is good and bad water (assume fountains by RRs)?, If only bad water in term where is a good deal for bottled?
3) Can you get it filled in flight?
4) Do you use filters of any kind?
5) Why do you do it?


1) Camelback Better Bottle .75L caribinered onto bag, Also have used 100oz Mule hydration pack(I was taking it for hiking anyway).
2) LGA=bad, DFW/BOS=Good, street fountains in Rome=awesome!^
3) AA FAs usually fill it half. Some say they can't puor into in my bottle for sanitary reasons.?!? I usually get it full when I ask to buy a bottle onboard.
4) MSR Miniworks EX(really for camping)
5)can't spill, save $$, I drink a lot or else I get migraines, don't like throwing away plastic(recycling is OK), bottled H2O isn't that great http://abcnews.go.com/Business/story?id=87558&page=1
