Chris Smith's website, www.portlandtransport.com, has the skinny on the reprint of our favorite Portland walking resource, Metro's Walk There! book:
My correspondent at Metro tells me that the Walk There guide is now available in an updated second edition, but is, unfortunately, no longer free. It is available for $9.95 from the Metro Data Resource Center and at local book stores.
Many of the walks are available as free downloadable PDFs from Metro's web site.
We also recommend you check out Metro's calendar which is full of guided walks this spring and summer led by walking guru and author (of Walk There! among others) Laura Foster.
