Been done but... "Suburban yards are often separated by fences that are 6 feet high. I doubt that a deer will jump one even if he could."

A Virginia White Tailed buck can clear near twice that. I have seen them clear silver birch deadfalls on the second jump from standing still WAY too many times (I used to hunt and found them the most elusive animal in our woods... them thar huntin shows on yer TV from down in the southern States ain't REAL huntin). Of course, ours are much bigger than most with the biggest of the big upwards of 300 pounds.

I've seen videos of elk in towns out west. Seems VERY dangerous to me.
