I'm not recommending you should do this, but some people in environmentalist groups used to spray expanding foam (available at Lowe's or Home Depot) up into the tailpipes of these sort of vehicles.
Little men and their big trucks. They get on my ass and try to intimidate me as I go to work every morning. Gas prices are going up and they'll be hurtin' pretty soon.
I gave some to my brother before I went overseas and he kept it for me until I got back a year or so later. I was hoping he'd smoke it, but his wife probably wouldn't let him. It was ok, but not real good.
If you let these people get to you, they've won. Some of these things you have some control over, but there's not much you can do for some of the other stuff. Move on with your life.
I spent a Christmas in Saudi Arabia (Log Base Alpha) during Operation Desert Shield. A few weeks later it would become Operation Desert Storm. It was kind of a depressing Christmas.
I've used MG because it's available anywhere. I have to drive several extra miles thru city traffiic to get that fancy stuff. Miracle Gro's good enough for SkidMark.
I'm also in my mid-50s and just shared with my daughter that I'm a pothead. I doubt we'll ever toke together (neither of us could probably handle that), but the cat's out of the bag. I hope we can share some buds in the near future.
It's good to find some people who don't rag on miracle gro. I've used it all along, but I just bought some happy frog and some other nutes from a hydro store for next time. We'll see what happens.
