if she drinks wine, a bottle of wine and 4 plastic wine "glasses" that won't break. I like the ones without stems because they fit in the drink holder on our outdoor chairs and won't tip over in the wind!
A note that says you are taking her somewhere on the next trip that she's always wanted to go. And give her a travel book from there.
Kindle if she likes to read. Gift card for Amazon.com or Barnes & Noble if she has a Kindle or Nook. A small pillow for reading.
Gas firepit.
I like "Life is Good" tee shirts. Cute colors, sayings and camping things on them. They have short sleeve and long sleeve. http://www.lifeisgood.com/gift-ideas/camping-and-hiking/
