You can road trip it from ID.
I poked around the website, what is conspicuously absent is a list of which employers are attending. Before you spend money you want to that the employers attending will be...
1. Appropriate for your experience level, ie don't pay money to talk to DAL, SWA, FDX if you have 250 hours.
2. Actually hiring, or planning on doing so soon.
Assuming you are very low time (<500 hours), there may not be many suitable employers attending...entry level employers can usually get enough people locally. Networking is good, but you need to be in the ballpark experience wise...a MLB team scout is not going to take a little-leaguer seriously.
