Jerslash,

I was taught to pick things up too, but.... I own and manage commercial real estate and used to pick litter up all the time. A colleague who did the same, caught hepatitis and was told it liekly came from picking-up some trash that he shouldn't have. I stopped picking-up trash unless I have golves or one of those remote grabber picker-upper thingies.

Not saying don't pick up trash. Just be carefull.
