Good that you survived with only small injuries. But can't say that you are lucky if you know what I mean. Take care!
In Russia we call those cagers who have accidential driving style DEERS. And there is one more confirmation that the term is found properly.
Also wear all the gear all the time...now. Previously had some incidents without any, only t-shirt and pants. But those were not so serious, the worst needed one month until full recovery.
Recently saw bad accident. The harley driver without any gear, just non-motorcycle leather jacket, jeans and glasses hit the cager-deer at about 50mph. Well, I stopped to help him - he had bruises all over his body, broken fingers, one foot separated, blood everywhere. Just made his blood losing stop, then called for ambulance, together made some bondages... then police... Was together with my girlfriend, tried to make her not see all this, but her knees were shaking. Well, hope that this guy will recover. After that there is no any thought about not using the armor.
