For drinks, I'm taking a cooler with some of these Bud Light Lime-a-Ritas on ice.

To me, they taste like a really good Mexican restaurant margarita. Not that I drink a lot of them, but of the ones I've had, this one ranks high. Particularly since they are so portable.
Then, for munchies, I'll pack some carrot and celery sticks, dip, and some quiche. There will be people renting the Brown Palace next door, and I hope they will bring some chips.

Crustless Spinach Quiche

1 chicken bouillon cube, crumbled
1/4 tsp nutmeg
Crumbled lettuce
1/4 tsp dry mustard
1/8 tsp cayenne
1 (13 oz) can evaporated milk
1 cup shredded process Swiss cheese*
6 crisp cooked bacon strips
Cook the spinach and drain well. Beat eggs with bouillon cube, nutmeg, dry mustard, and cayenne. Stir in undiluted milk. Add cheese, drained spinach, onion, and bacon, mixing well. Turn into a shallow 1 1/2 qt cake pan (8 1/2 inch size). Set in a pan with 1 inch hot water. Bake on center shelf of preheated 375 degree oven for 35 to 40 minutes or until knife tests clean. Let stand 10 minutes. Serve warm or cold on crisp lettuce.
*I'm going to use regular Swiss. Don't know if it will melt as smoothly as the processed version, but I don't care.
