My husband and I still celebrate when we first started dating, this will be our 5th... I need ideas on a gift.?

We still celebrate it as one of our anniversaries. I would like to get something that will really mean something not just to him but for both of us nothing outrageously expensive either. But I would like to have some ideas. Don't say sex or lingerie, because everyone knows that is a definite gift idea. Please help...thanks.
