Mini Thumper, can't help with the location.
Sweet talking the hubby, well, that's easy. You tell him all about the Reno ride that you missed out on, how cool all these women are, how Girlrider is competing in the SSDT this year, competed in the Trials des Nations (her first year of trials, way to go!!!) last year & the ISDE (bronze medal) the year before - so is a damned good rider. You then check out the following threads (no, you've checked them out already, so can show him pix & explain what they all learnt):

(page 10 of this forum if the links don't work) - actually have a look around about pg10 & 11 for more ammo.
You point out how much time he spends racing & how you help him out, how you'd love to meet these people & it'll help no end with your confidence. You then ask him what he's recently bought for his bike & is $100 or so really too much for you to spend on yourself? (I don't think many guys would be able to argue with that one, heck, I could just about afford to be able to come over for it if it wasn't for the fact of what I've spent on his bikes this month). Hmmm, will work on him for that one, but will have to give him advance warning so he can save up.
Now, if none of my ideas work, there's always the *other* bribe.
Seriously though, if you can make it, go.
