My input on Portland:
For food: Paradox Cafe on Belmont or Bay Leaf on Division. Lots more on here:

For biking: If you like biking in the city then go mess around in the NW or SE neighborhoods. If you want nature and climbing hills, head up towards the zoo. If you like recreational riding hop on Spring water Corridor trail under the east side of the hawthorne bridge (the green one).
For bars: I like good beer, so the Rogue public house is great. The horse brass has more taps than I know what to do with is low key English style pub. If you like something more trendy then try Henry's downtown.
For camping: I dunno in town. The closest place I have camped is at Oxbow park which is at least 30-45 minute drive east of Gresham.
