i remember one time me and some friends were sitting in my car smoking a bowl in a friend's trailer park (we could not smoke in the house because my friend's roomate cant stand the smell and at the time was paying all the bills) and the neighbor came out on his porch and 5 min later we see a cop car coming around the corner fortunately we saw him b4 he saw us and we ran back into the house and looked out the window and sure enough he stopped by my car and started shining his flashlight around what really burned me about that is that it was like 2 in the morning and that a**hole neighbor had nothing better to do

but i smoke in public all the time when im driving, walking down the street or sitting on the front porch just the other day me and my good friend were hitting up a waterfall bong we just made in his front yard in broad daylight and there were people walking/driving by and nobody did anything but that could be because it was right in the middle of the hood (North side of Flint MI)
we sure got some strange looks from some people though because lighting a waterfall is a strange process
