so you would think that gives you the right to put them where ever you like when ever you like.

do you get the contents of your recyling bin and put in on peoples yards and in shopping centres cause you want to prove a point with the response "its recyclable"

it may be - but you are offending people that use the items you have an issue with, you are causing increase in workload for the people who have to get them all off and making unneccarry rubbish to recycle.

BUild up some courage and pen to paper instead and stop being a secret squirrel protestor
