Yep, book is available at
www.wrxvsevo.com, and also it is on Amazon. You may find it at some other online retailers, but you're sure to find it at either of those.
Not sure if you'll ever find it at the big retailers like B&N and Borders. Those guys have been subtracting shelf space for transportation in a big way the last couple years.
Someone at the show mentioned that it was written up in Super Street or Modified a little while back--anyone out there remember which magazine/issue? We sent review copies to both, I believe.
