Using conventional techniques and not venturing anywhere near the center of the galaxy, I bet one can do some fly-bys to reach galactic escape velocity. Heck, using unconventional techniques, such as nuclear pulse propulsion, the thinking it one can reach 10 PSOL, so it shouldn't be that hard. Or one might just find a rogue star or planet and try to get captured by it. :)
