The Yards parking lots across First Street are a good option and are not listed on the Nats page 'cause they're operated privately. Go to http://www.networkparking.net/theyardsbaseball/index.shtml for information.
They're cheaper ($15-$25) than comparable Nats lots and they allow some tailgating (but no grilling.)
You get reduced rates (by $5) if you buy 20 or more passes. Best thing is that you don't have to buy for a whole season. That's ideal for ticket groups who have some members who want parking and some who don't.
Thanks for the tip on the reduced rates, the one problem is that you have to select your 20 games at the time of purchase, but the guy did say that they will allow exchanges for missed games.
I need to call back and find out if this means that they reserve a spot for me in cases like opening day when the lots fill up early.
