Remember the U.S. Conference of Mayors held in Salt Lake City last summer? Michael Dukakis came; so did Jesse Jackson; George Bush didn't.

Well, Salt Lake City still has $28,000 left over from the money raised to entertain 170 mayors at the conference, and officials are trying to figure out what to do with it.Mayor Palmer DePaulis will send a letter soon thanking the 28 Salt Lake businesses that contributed $500 to $25,000 to the June 10-15 event and suggesting two alternatives for using the money, an aide said.

"Thanks to you and the generosity of many organizations, Salt Lake City was able to finish this event with a cash surplus," a draft of the letter said.

The first option suggested by DePaulis is that contributors be returned a percentage of the surplus based on their contribution. The second alternative enables the city to keep the money and use it to attract other big-name conferences, the letter said.

The city raised $145,800 in cash and in-kind contributions for the event and even set aside $40,000 in city money to cover unforeseen costs at the event, said Emilie Charles, executive assistant to the mayor.

But the city spent only $117,800 without even touching the $40,000 contingency, which was returned to the city's general fund. That left the $28,000 bonus.

The city anticipated 1,000 mayors at the event but only 700 attended, significantly reducing costs. And the crowd that did come may have consisted of more teetotalers than expected. The city returned $3,878 in liquor following the conference, Charles said.
