Or better yet, go down to a BBQ place and order a pulled pork sandwich.
Much easier than preparing an imu. Have you ever done that? Lots of work but kalua pig is indeed yummy. I participated in one moons ago in Oregon. But the river rocks gathered had not been fire heated before. They were imu virgins.
Some of the hot rocks exploded underground and imbedded the pork with rock shrapnel. Needless to say we were some unhappy campers. Dumb haoles!
