What's really remarkable, which Vae Victus hasn't pointed out, is that they're near ground zero for the massive snow storm that dumped a couple of feet on Virginia. I'm very impressed.

Put some aluminum sheet (1/16" or thinner) metal on your wooden defenses and round the edges a bit. We've found that it makes a slight difference on the moat and rock wall traversal with full weight. It's not HUGE, but if you're detail oriented you'll want to try it.
