It was a lovely day full of beautiful memories, as 300 guests gathered with us to witness our marriage vows. There’s a reason you have people stand beside you when you get married—and many of those people are still very dear to us now 30 years later.

It’s been an adventure from the start and I can’t wait to see what our future brings!

true love chocolate cakeLife is full of twists and turns and hard times, but also beautiful, loving, tender moments.

Some thoughts I’ve learned along the way:

*Love and respect will get your through most anything.
*Love is a verb–full of action as well as a feeling.
*Learn to say I forgive you, or will you forgive me?
*Be a dreamer with your spouse.
*Don’t stop praying.
*Don’t complain about your spouse to others.
*Laugh a lot. I mean, a lot.
