Each of the 125 National Park System areas that provides angling opportunities is listed here, by state, with coverage ranging from one page (Devil's Tower National Monument) to 17 (Yellowstone). Each entry includes information on access, species, license requirements, camping regulations, and, where appropriate, even the emergence dates of the major aquatic hatches. Of particular interest is a brief treatment of additional useful publications and articles on the sites discussed. The most comprehensive reference of its kind, this is of equal value to experienced anglers unfamiliar with particular waters and to vacationing families who want to give the kids a morning's fishing. Recommended for travel and sports fishing collections.-- David J. Panciera, Westerly P.L., R.I.
