Yes, SLNT is still alive and well. Have you not heard of the TNT? We usually fun fly at two different sites. Eastfield College on the southeast side of Dallas is our primary AMA insured site for fun flying and small contests. SH 407 @ I35E north of Lewisville is a rouge field we meet at quite often as well to fun fly.
Here's a link to our web site. You can sign up for e-mail notifications of fun fly sessions there as well. Don't know how much action we will have this week with turkey day and all. PM me if you like, I'll try to respond as soon as I can, this week is still a work week for me.
