Hi Evan,
I use calf panels for fencing and greenhouse/shadehouse, with both I force them into an arc. Having lived in high deer population pressure areas (Humboldt County in N.CA, Orcas Island, WA) clever tricks like high flags above fence, soap, adult male human urine, coyote piss, etc. only work when either population is low or other deer food options exist. I've seen a wiley deer force themselves under a poorly anchored fence too. I have observed that an outer fence set at 45 degrees 6' feet out from the inner vertical fence seems to discourage deer from walking up to then leaping over the fence.
