Thanks for the info on portland, oregon. A good guide for travellers.

Interesting and informative reading

Neat article and timely as the area of Ohio I live in has been going through quite a rainy spell. We haven't seen the sun much. Sudies have shown that this can have a definate impact on the moral of the populace. Voted up.
