At an election forum this week, mayoral candidate Augustus Cho got the first crack at the question, "What is your position on the rural perimeter?" (That's the boundary that keeps development in Chapel Hill and Carrboro roughly south of I-40 and Eubanks Road, east of Old 86 and north of Highway 54). 

"Moral parameter?" asked Cho. "Was that the question?"

"I think I've heard that one before," said opponent Kevin Wolff.

"No, the rural perimeter," said moderator Jan Richmond, past presdent of the local League of Women Voters.

"I'm sorry," said Cho. "No cheap shot; I didn't mean to."

Cho, like all the other mayoral candidates, said he favored keeping the rural buffer.
