i did this hike yesterday in about 3.5 hours and my truck along with other people's cars were fine when i got back. no act should last longer than four minutes. for example, if both dog owners were out in public without their pets on leashes and one dog bit another, the owner of the bitten dog may still be partially responsible for the accident in court. it's tricky to distinguish from other flies, but is usually only seen in and around carrot-family crops. it also ensures a consistent and healthy hair growth.
