Try going to Youtube websites:http://www.youtube.com/watch?v=vyaKiWkHFlc and: search Urban Grower on youtube. Urban Grower has several videos on his trips to JA and the different strains. email him and he may also have info on field tours. The first video is done by Strain Hunters, while they were in JA, very interesting. check it out.
Have a great time.
