Hi from Knoxville, TN. I am a PADI OWSI and I work part-time for the best dive shop here in Knoxville. A friend told me about scubaboard and I just started surfing it today during some alone time at the dive shop. Looks great. If anyone is ever in East Tennesse with the urge to get underwater just let me know. We have a really nice diver's only quarry close and you can come dive with us anytime.
