I'll be interested to see if they have any kind of program for sending the Lexan bottles back to Nalgene--doesn't seem that likely though. Maybe the best thing is to think of other uses for them if they can't be easily recycled. Any ideas? I have a couple of those bottles sitting on the shelf and am thinking of using them to put gorp and the like in for hiking trips. Solids shouldn't really pick up BPA from the plastic like liquids do, I don't think. At least if they're not stored for long periods in the bottles.
