Well equipped regional airport with full facilties but (when we visited) little commercial traffic and no other GA aircraft on the huge parking apron. After landing, switch to operations frequency for parking/handling/marshalling etc. Friendly staff. Exit/entry through separate door with own security check leading into a small lounge/seating shared with airport office to pay landing fees. Fixed AVGAS pump takes credit cards. Frequent bus service outside the terminal also plenty of taxis. The city itself is fairly industrial and business oriented.
