Another in the ``road trip'' series, this guide to baseball in the minors follows Dan Valenti's Cactus League Road Trip ( LJ 12/1/89). After touching on the minors' history, Greenberg gives--for each team from top minors on down--address, stadium and ticket details, capsule history, and some noted graduates. He covers also rookie and summer leagues and major league farm systems. More information on each of the lower clubs is in The Whole Baseball Catalogue ( LJ 2/15/90) and Baseball America's annuals (PO Box 2089, Durham, NC 27702), which has schedules as well. While these are preferred for reference, The Minor League Road Trip is an acceptable guide for the baseball tourist.--Morey Berger, formerly with Monmouth Cty. Lib., Manalapan, N.J.
