I originally planned to do the asphalt and yellow belly and make my own, it just isn't worth it. I only paid $100 more for my freeway male compared to what 100% asphalts are going for. You can save money going the asphalt/yb route but that's a huge risk of wasting time. I already have a few female combos with yellow belly, some already breeding. So now instead of growing out a snake that doesn't look much better than a normal, I'm enjoying a freeway and now next year I'll be creating my own, new, freeway combos instead of just a freeway.
