After a long day at work, I arrive back at the Centennial Hills Park and Ride only to find a dead battery. I haven't lived here that long so don't have any friends or relatives that I could call to bail me out. Thanks Yelp. Found these guys and they were great. Being in the upper northwest end of the valley, I figured I'd have to wait a couple of hours, but no. Vegas Towing Service (Big Valley Towing) was there in about a half hour! They were friendly and very professional. They jumped me and confirmed that I did indeed need a new battery. Big Valley Towing really turned a bummer into a non-event. I will always call Big Valley Towing. Thanks guys!
