British and Canadian companies www.envyrobubble.com & www.gummybin.com have created these cute gum recycling bins. Kinda seems excessive, just another place to post an ad but there is nothing worse than stepping in gum. And it probably takes some pretty harsh chemos to remove gum from the sidewalks and such.
And if you were wondering DR is not a litterbug, that's not why the post is dedicated to him....
