Oklahoma City and San Antonio are connected by I-35, the north-south interstate highway that runs from Laredo, Texas, to Duluth, Minn. The 466 miles between OKC and San Antonio don’t exactly make for a Subway Series, but sharing a major artery provides a degree of geographic connection. In that way the OKC-San Antonio matchup is bit reminiscent of the 1985 World Series, which shuttled between St. Louis and Kansas City on I-70 and what was known as the “I-70 Showdown Series.”
