Due to repeated snow-outs, the Indians are relocating to Milwaukee for their next series against the Angels.  This marks the first time that anyone went to Milwaukee for the weather.

The last time a team had to relocate to another stadium unexpectedly was September 13-14, 2004 when the Marlins moved a series to the new Comiskey due to Hurricane Ivan.  In 1998, a beam fell in Yankee Stadium and the Yanks ended up playing a matinee at Shea on April 15 while the Mets played host that night.  In 1997, the Padres moved a series to Honolulu due to construction to Qualcomm in preparation for the Super Bowl.  In 1996 Oakland Coliseum was under construction for the newly returned Raiders and the A's played a series in Vegas.

Prior to this, teams typically played in other stadiums as a promotion.  The White Sox played in Milwaukee in the late Sixties as a sop to fans in the fallow years between the Braves and the Brewers.  The Dodgers played some games in Jersey City before relocating permanently to LA. 

However, the topper was in 1946 when the Braves had to relocate temporary to Fenway because of a bad paint job.  After painting the bleachers green, the team was waylaid by angry fans with green paint all over the keisters. 

Here are all the instances of teams playing in a home away from home in the so-called modern era.  I would include the nineteenth century, but there were just too many instances.  Note that teams still won at a decent clip (.536 winning percentage) in theor temporary homes:
