>>1664647just basic blackberry bushes are miserable- huge tangles of thorns that are very hard to get rid of.
another- foxtails. not so bad for humans but brutal for dogs. The tip when dry is hard and sharp as a needle. they are serated and go in smooth like silk but cant be pulled out cuz of bushy spikes. My dog got one embedded in his scrotum once. not good.
