Tejada - buy her a very nice chair, I like the one that comes in a carry bag that has the attached feet holder that keeps our legs elevated.
Mine is with 2 cupholders - (1 is for diet coke, the other is for cigarettes.) Maybe a big umbrella if sun is the issue. Be sure to carry all this stuff for her. Also a bag of red twizzlers. Tell her she can have free reading time out doors, or relax time all very comfortable.
I didn't really care much for baseball either. It was a slow evolving process. But I liked going out, my husband 'splained everything to me that I eventually had a question about. I came around to care about the game, and that my stepson played.
Is your wife hispanic? I only ask because my husband is and I am not. Seemed to be a lot for me to learn if I was to participate in such a huge part of my husband. He is from Nicaragua, and played professionally there back in the day. I'm glad I learned to love baseball. Now, I'm even more up on MLB teams and players than he is.
