I am doing San Francisco <---> Portland, Oregon right now. In theory it sounds great. I get access to a huge tech/startup city while also having a more relaxed, quirky Portland. My girlfriend is in Portland, and my sister is in San Francisco, so I have a vested interested in spending equal time in both cities. But after 5-6 months, I just got tired of the back and forth traveling. I felt like I couldn't invest socially in one city. Planning meetings, events, etc also became difficult because my time in both cities was split in half (I was going down to SF 2 weeks a month, sometimes 1 week a month).
