Going through some files I came across a booklet, "Minor Trips: A Traveler's Guide to Minor League Baseball and Independent Professional Baseball." An RVing baseball fan could see baseball games in many states as they RV travel. This guide can only be purchased by sending a check to:
Minor Trips, PO Box 360105, Strongsville, OH 44136.
You can write the publisher, Bob Carson, at MinorTrips@aol.com to find out the price. He also publishes a newsletter twice a year, which people seem to enjoy reading. I've seen $6 for the guidebook and $15 for a subscription and the guidebook. His newsletter is a wealth of information.
There are a couple of other guides on minor league baseball available through Amazon as well. Bob's is updated yearly.
Another opportunity to watch baseball comes earlier in the spring is during spring training. Games are played during February and March. SpringTrainingOnline.com has schedules and other information. If you want to be more involved, you could get a job to work during the games. These jobs are advertised locally ahead of time or Google "spring training jobs" in December or January.
