Yeah I'm not much of an organizer either. Then again the whole organizing bit is just about the 10% discount. We could also just all decide to sign up at regular price on some future date and go. I tend to be at all of their events at the MSR Houston track anyways, it's sort of become my home track/event about every 2 months.
I'm going to start branching out a little more with Texas World Speedway this year as well (and a completely different program down at Grandsport Speedway -
Grandsport Speedway - Houston, Texas - I haven't been down there yet).
MSR Houston is a really nice track to learn on though, because it's pretty much idiot-proof on spinouts with a generous runoff area of pavement and then grass around most of the track. Only one short straight has a wall next to it, and it's easy to just take the entry a little easy on that straight to be safe. The track surface is also a bit ripply in places, which really helps with learning to smooth your inputs and control the car, ironically.
I can't stress enough what a good experience the program has been for me overall. You think you know how to drive until you get out to a few of these events... you really don't. I still really don't. It's a constant learning process, and the results definitely apply back to everyday driving as well. Smooth inputs, proper braking and cornering, managing traction in wet conditions, training your brain and eyes to be vastly more situationally aware of what's going on way down the road in every direction, etc...
