OH I can't wait for the lawsuits on burning down grasslands caused by the particulate filters. Farmers are exempt from having cats on gas powered trucks because of this (in many states not all by any stretch) so how many fields and wildfires are going to be started by these and with no way to remove them farmers are just not going to be able to drive thier trucks across grassland areas or hayfields or wheat stubble fields because they will cause fires just like the cats did when they first came out. Oh well I guess farmers don't buy very many diesel pickups anyway<a href="http://plugin.smileycentral.com/http%253A%252F%252Fwww.smileycentral.com%252F%253F partner%253DZSzeb008%255FZNfox000%25283%2529%2526i %253D23%252F23%255F3%255F60%2526feat%253Dprof/page.html" target="_blank"><img src="http://smileys.smileycentral.com/cat/23/23_3_60.gif" alt="SmileyCentral.com" border="0"><img border="0" src="http://plugin.smileycentral.com/http%253A%252F%252Fimgfarm%252Ecom%252Fimages%252F nocache%252Ftr%252Ffw%252Fsmiley%252Fsocial%252Egi f%253Fi%253D23%252F23_3_60/image.gif"></a>
