Next year will be in Washington, DC. I encourage anyone who really wants to attend a National to start saving for it NOW.
Seriously. Tell everyone in your family that all you want for any kind of gift is cash money for your National fund. ("Forget chocolate for Valentine's Day, dear, gimme the $15 bucks instead. It's going into the National stash!")
Even if it takes you two years (two years from now, I believe it's going to be in Nashville) or more to save up for it -- if it's something you really want, make a plan to accomplish it. Don't wait until this time next year and wonder how to make it happen.
I mean, this is a much better gift than, oh, say, new pajamas for Christmas, right? Perfume for your birthday?
Put all your pocket change in a designated jar. It's amazing how that stuff adds up.

Skip the Starbucks, put the money in the jar.
Sell some stuff on eBay.
I want to see YOU at National sometime.

Make it happen!
And you do get a discount for the registration if you give a workshop. Actually, it's more of a rebate -- you have to pay the full price upfront, and then you get money LATER, after the conference. (That's so they make sure you actually showed up and gave the workshop.) I don't remember what the rebate is anymore. It doesn't cover the whole thing. But consider submitting a proposal. There's no guarantee you'll be selected, but if you are, that can help defray the costs.
