The only active ship I know of in the Los Angeles area is the
IKRV Hurgh Hap, which has the distinction of being the only research vessel in the fleet. If I were based in the area I would definitely try to meet the crew and look into joining. Explore its website and contact Captain HaghwuS at | haghwus2 at aol dot com | for more information.
As to joining a house...? You may wish to look through
our listings of line histories to see if any of them appeal to you. If so most of the posters still have contact information available through their profiles. Unfortunately, the highly promising
Imperial Klingon Line Registry Database is down at the moment. Does anyone else have advice to give our newcomer in finding and joining a house?
