we used to refer to really good reefer as being "45 mph" weed. no matter how hard you tried you'd end up going 45 mph, and wondering where the fuck you were. those were the good old days of the "tatum night riders". pile a bunch of heads into your mom's station wagon and head out onto the back roads of tatum, sc. the trip would usually culminate with a visit to bigfoot road. rarely drive while smoking these days though. it isn't worth the risk.
