Rain ruins everything

Traveling for baseball is tricky, especially when it's an open concept stadium. I have now experienced 2 postponed game. It sucks.. 

This last game in Atlanta isn't as easy to come back to. I was lucky in Chicago, as there was a day in between. I got to relish in the fact that I was able to just change a flight and go. Not all games are designed for weather. this isn't anything MLB can change, or is it?

Should it be mandated for stadiums to be enclosed?
