SFB--worth the trip?

Allegiant Air is opening a TYS-SFB route in early 2007. The fares are quite reasonable, and im not a very picky person as far as flights/amenities are concerned. My question, is SFB “spotter friendly” in any aspect? They seem to have some interesting airline arrivals and departures. I am aware that there are many other options in the U.S. to view aircraft, but living in East Tennessee, any decently priced fare to anywhere from this area is worth the trip.
Thanks for any info.
