This album has a lot of very cool Cheech & Chong routines on it. They are classics of the genre, and much funnier than some of the stuff that shows up in their films.
My sister had it when she was in High School, and I used to borrow it. The vinyl album had a great pull out sleeve that showed all the hidden drugs in compartments in the VW Bug on the cover.
I recommend it to anyone who enjoys this kind of humor, wants a blast from the past (70s style), or just wants to check out Cheech Marin before he went 'respectable' and straight (drug-wise). I can't wait to listen to it again, this time on CD.
