Most of the time trees are no longer in their natural, upright state. They could be upright, but unstable. Other trees may even be resting on them. Worse than that, they may be fallen or partially fallen onto downed power lines or vehicles and across roadways. Broken tree parts are often dangling above your head.
Do not hesitate! After a storm in Northern Nevada, there is only one logical thing to do. That is call The Tree Professional at this phone number (775) 420-8694. Greg (and maybe one of his crew) will come to your location in the Reno area. Count on The Tree Professional to remove downed and dangerous trees. See their acrobatics at thetreeprofessional.com.
