MARPAT I think works the best for out here in Colorado Rockies. The regular Woodland, CADPAT or Tiger Stripe worked very well when I was living in the very green jungle like state of Maryland.

3 color desert, tan accessories for "GP Hunting".

You are standing by the treetrunks, not leaves.   Otherwise you are standing in grass (not green in fall, in midwest).

Depends on your terrain, the time of year, and if the water is still running.

I have three patterns and black. Desert camo in both six color "chocolate chip" and three color. Both work well out in the desert, the three color a tiny bit better in the rocks, and the six color a tiny bit better in the scrub brush. Wearing either and being still a human isn't noticable even at 50 yards. The woodland pattern works in my urban enviornment until the water stops running and then it's desert camo time.

I've got four sets of slightly used woodland (work BDU's), and two sets each of the deserts. My wife has a set of fleckar and I think she wants desert next.

Quoted: American Legion is selling tricolor desert (supposedly milspec) for $24.95/$29.95.  Is this a good deal?

Shuffle through EE Mil Spec Gear once a month or so.  You can get NIW BDU shirts in varied designs for $20, usually complete sets available too if you don't mind used/ok.
