The mayor and council members serve four-year terms.
Each of them get the minimum amount, $37.06, off their quarterly water bills. The mayor also receives a $180 monthly gas allowance, Town Clerk/Treasurer Brenda L. Haynes has said.
Kline is facing opposition in the mayoral race for the first time since he became mayor as a write-in candidate in 1982, he has said.
Kline said he wants to continue as mayor so he can "serve the people."
Asked what he thought about Crampton running against him, Kline said, "It's a free country."
Kline, 80, is a retired teacher. He served on the town council for about two years before he was mayor. He served on the Washington County Board of Education from 1994 to 1998.
Crampton, 49, is halfway through his four-year term as assistant mayor. He has been assistant mayor since 1992. He is president of Paul Crampton Contractors.
Asked if serving on the council or as mayor is a conflict of interest for him because he is a local developer, Crampton said he has abstained from any decisions he or Haynes have thought he shouldn't get involved in because of his job as a developer.
Crampton said his job has allowed him to "pull" a lot of help and commitments to get things done for the town at a reduced cost, either from his business or other businesses.
"Instead of being a deterrent, it's definitely been a benefit," Crampton said.
Crampton said he would like to put his experience as a town council member to good use as mayor.
Gaver, 49, said he's helped organize Olde Tyme Christmas for the last 10 years and, for the second year, is helping organize Day in the Park.
"Basically, I'm already working with the town," Gaver said. "I want to get a little more involved with what's going on in town."
Gaver is an inspector with Washington County Permits & Inspections and teaches electrical courses at Frederick (Md.) Community College. He ran unsuccessfully for council in 2000, 2002 and 2004.
Nigh, 82, said he filed to keep his seat because he enjoys serving on the council. A retiree, Nigh served in the U.S. Army, worked at M.P. Moller Inc. and was a correctional officer with the state prison system south of Hagerstown.
Asked if there was anything specific he wanted to accomplish, Nigh said, "Nothing. I'm 82. I've been there (on the council) since 1990. I thought, well, I'm going to try four more."
