Transit Map Water Bottles

I suspect many of the people reading this are interested in finding transit related memorabilia either to buy themselves or to put on wish lists for friends and family to consider purchasing as a gift.  Here’s one potential purchase idea that was brought to my attention recently: a transit map water bottle.  The online store at Planetizen has water bottles with transit maps from several different cities on them, including DC, New York, Chicago, San Francisco, and Austin. Check them out here.
