I could sure use some help with a big anniversary any ideas?

We are going to be celebrating 30 years together not to long from now. I need some ideas that are not to hard on the pocket we're both on fixed incomes. I figure if I get some ideas I can work on on saving enough money as it's about 5 1/2 months. She's not into things like parties. It's going to be hard to top her Christmas gift, she has always dreamed of having a Grandfather clock, she got one. There really isn't anything else I can think of that she wants so I'm open to ideas.
