You could call them intercollegiate friendships, and they are an important part of the College World Series.
Over the years, Omaha CWS fans have forged relationships with fans who travel here from such places as Louisiana, Texas and Mississippi to catch a little baseball in June.
Some of the friendships stretch back decades and turn the CWS into a family reunion with baseball roots.
The bonding often starts at tailgate parties when out-of-state fans set up a grill next to an Omaha group. Pretty soon, Louisiana fans are sharing crawfish, and Omaha folks are offering them tasty Nebraska beef and a cold drink.
Even though the friendships might start with food and baseball, they are about more than that.
Omaha fans and their out-of-state buddies stay in touch throughout the year. They visit each other, trade emails and phone calls, know the names of kids and grandkids, and send gifts and cards at Christmastime.
Two Omaha-area couples even went to the recent Louisiana wedding of the daughter of friends they met at the CWS more than a decade ago.
The friendships fit well with the CWS fan vibe, one fueled as much by camaraderie as competition.
