From San Diego...PCH101 north of Santa Barbara up the California Coast, up the Oregon Coast, up the Washington Coast. Once up here: Olympic NP; WA-20 through N. Cascades National Park; head down to Mt. Rainier NP/Mt. St. Helens; head south to/through the Columbia Gorge; Mt. Hood. (From here I'll let the Oregonians take over.)
Plan on a couple of weeks for my suggested itinerary alone. You're a long way from Long Island so take your time and see what you can while you're here. The Pacific N.W. is a huge area.
