oh, i wasn't questioning the trailer....i was doubting the fact a deer would jump that high under that circumstance.
I'm no expert on deer jumping heights, but deer are a special creature that tend to only look eye level and down. for them to jump they need to look up, and they need to see the object they intend to jump over. Looking up is something they rarely do, which is why deer stands for hunting are so successful.
When they approach a fence they will look up, judge the distance and jump if they can make it. Some reports are 12', most good sized whitetails can easily clear 8' fences.
I really doubt a deer while crossing a road is ever going to look skyward and use jumping as a defence. They're looking at the forest the other side and will run as a defence, bound if necessary, but I do not ever think a deer has the intellgence to use the huge leap skyward as a defence, and then suddenly find themselves by chance crashing thru the tarp.
Just don't think it's a credible story.
