Doing the contact training at Orange Grove vs. Cabaniss always seemd like a good deal to me. It's been a while now, but I remember that the one day we had to stay local for our contact work (wx must have socked in the south) the "MOA" they use off the coast and the 3 transition fields were super crowded w/ tower calling every base turn, multiple go-arounds for proximity, etc. whereas in the C-12 we would have the area all to ourselves, then head down to Orange Grove and be one of 2 or 3 in the pattern. It went quicker and I felt like i learned more.
Honestly though, above all I'd reccomend going in on a house on the island w/ a couple dudes and just make sure you are in the same squadron as them. Even a better deal if they are a class ahead of you!
