What is the reasons of price hiking?

My dad and I were looking for some good hiking trails. We live in Vancouver, Washington.

I want to be fit to do some hiking this coming summer. Are there any online workouts that will improve my physical condition and make hiking easier? I will be hiking with a 20 lb. Pack then.

Where is a good inexpensive place that is private, where you can go rafting, hiking, mountain climbing (possibly), and camping. Id like a list of possibilities, if you could, of different places that I could go. And I'm not talking about tourist traps.

First off, where is the hiking selection. Come on guys, people don't ask about hiking? Secondly, I have hiked in several surrounding areas of Muskegon. I need more exciting, prettier hikes. Anyone have any good suggestions? Also I am bringing someone along at one point or another that hates...

Can any one advice me about real reasons of recent food price hike. (ie. Direct, indirect reasons, impact of Govt. Policies, Open trade policy etc.)
