Despite the dreary weather, about 10 gay couples made the trip to Phoenix City Hall Monday morning to be among the first to register with the city as domestic partners.

The registry, which is open to unmarried gay or straight couples who share a Phoenix residence, grants partner visitation rights in all hospitals, nursing homes, rehabilitation centers and other health-care facilities in the city.

"It's sad that we have to deem this a huge deal, but this is a step in the right direction," said Lisa Smith, 41, standing with her partner, Reagan Bennion moments after signing up and paying a $50 registration fee. "Progress is progress, and we're here to support those who made this possible."

The couple has been dating for a year and became engaged a few months ago. They arrived before the registry officially opened at 9 a.m. in case there was a crowd.

Yet there were no lines early Monday and the initial turnout to register was lower than city officials had expected.

"We got up early and wanted to be first," said Bennion, 28.

Registration continues on the ground floor of City Hall in Assembly Room B through Friday. After that, partners can register on the 15th floor at the City Clerk Department.

The City Council voted in December to create the registry, making Phoenix the second city in the state to offer such a program. Tucson created a similar registry in 2003.

A fact sheet outlining requirements for the new registry is available at phoenix.gov.
