Wife and I "camped" in our motor coach for (5) days at Valley of Fire State Park in mid April. Being a Nevada resident for about a year I am learning the state/county/city "rules". While at the visitor center paying for my camping and getting an annual state parks pass from the regular ranger I noticed the law enforcement ranger in the office. He saw my NAVY ballcap and said hi.
While he was patrolling through the campground, I stopped and asked him the rules on open carrying. He said although the park is relatively safe feel free to open carry anywhere in the park for personal protection. Said only no no was discharging firearm for other than self defense. He was born and raised in Overton, NV and we talked for a good (10) minutes about the park, hiking and things to do.
When ever he saw me while patrolling, he would always stop and ask how my stay was going. He and Ray (regular ranger) were some of the nicest, professional national/state rangers I have ever encountered and acted like they were there to serve the visitors and not harass them.
