Supporters of gay marriage will be gathering in downtown Bend at the corner of Greenwood and Wall on Tuesday to show their support.
Oregon's Attorney General has decided not to defend the marriage ban so the judge will only be hearing arguments to get rid of it.
Ron Berry of Bend says he feels the tide is turning on this issue.
"We're feeling pretty optimistic, but we don't want to count our chickens before they're hatched. We've got a back up plan if he doesn't rule in our favor or in time. We will submit it to the ballot."
Supporters of gay marriage have gathered signatures on petitions to put the issue on the November ballot. They are waiting to see if that is necessary -- depending on how the judge rules.
It is not known when Judge Michael McShane is expected to rule, but the deadline to put the issue on the November ballot is early July.
