Mets are Grapefruit. I believe the dividing line for Grapefruit/Cactus is now the Pennsylvania/Ohio line with the exception of Minnesota, Houston, Detroit, and St. Louis (Grapefruit). I have been to games in both "Leagues" - I'll take the Cactus over the Grapefruit any day. The scenery around the parks is better, the people (employees/fellow tourists) are nicer, the spring training locations are closer together, and the weather is 80 and dry. My first trip to Spring Training was 1981 in Sarasota (White Sox/Tigers). I literally bumped into Al Kaline, it was a couple of bucks to get in. Now, they are bleeding you to get in. I seem to recall a couple of years ago, the remaining tickets (average tickets) for a Mets/Cards game were $150 per. I could afford it but passed, I didn't wish to be a party to such bloodsucking.
PS - Before my time during WWII (1943), baseball was asked to save "man-miles", so spring training was up north. Indiana for midwest teams and the north east for other teams. The Dodgers were up at Bear Mountain/West Point at off-hour times from the Army, the Boston Braves were ten miles away from my current residence at Choate (not Rosemary yet) Hall in Wallingford, CT, and the Yanks could have sent well wishes via a future Springsteen Album "Greetings from Asbury Park"
