MARTA's shuttle bus from Underground Atlanta to Turner Field could still run this baseball season, according to the Atlanta Journal-Constitution's Ariel Hart. Last summer the shuttle was set to get the axe, though MARTA now says they'll hold March 21 and March 24 public hearings on the matter after hearing "loud and clear" from the Atlanta Braves and their fans.

During last summer's battle over the shuttle, Talking Chop presented a lengthy resource on potential ways to fix the situation, including route alterations, bringing on a private company, and reducing the number of buses. The loss of shuttle routes would surely impact team attendance, since it's strenuous enough for OTPers to get within striking distance of the Ted as it is.
