Pioneer Square, although one of Portland's best known tourist destinations is also one of the coolest places in downtown. It's a large open courtyard with free wifi (which I'm using now) food vendors, coffee, public transit and shopping surrounding it.
There is always something happening, and it's a pretty sure-fire place to get in some good people watching.
On another note, I apologize for the somewhat crappy photos, these were taken with photobooth on my macbook. Currently, my camera is stuck in Alaska. Mega sadface. I promise my photography is much better than this! You can see some of my real photos under the "Portland" page.
Now, if you'll excuse me, some too-expensive-for-my-college-budget-but-I-don't-care clothing needs to get bought. Mommy sent me an easter basket and this was in it. <3 mamma.
