How do we get there from here?

Okay, so summer's only a couple of weeks away.  This year we're planning to go up to Seattle for several days, then over to Salmon, Idaho, and back home.  Where to go along the way?  Here are some places on our list for consideration:

• Grand Canyon
• DisneyLand
• Yosemite
• Crater Lake

Yikes -- It's looking like 5,500+ miles.
