Query: flawed

this book is riddled with flaws. the directions are misleading and dangerous. i have gotten lost on many of these excursions due to his poor trail descriptions. one will also be mislead by his money grubbing tactics. once you purchase the book you are lead to believe that you are allowed access to all of the holes in the book, but guess what? no. you have to join the serria club to get full access. lame, everyone knows the serria club is a cruel animal killing fratfest. i doubt this review will even stay up long enough to read because pancho is notorious for deleting these things the second they are written. i write this in the least slanderous way possible, but, he is in this for the money, not the love of swimmin. i recommend chris shaffer's book "the definitive guide to waterfalls of southern and central california" much better descriptions of waterfalls with swimmin holes with SAFE directions to and from.
