they have problems at times at SC but heck they problems at all the lakes, thefts at alamo and roosevelt so it can happen anywhere, they do have a gang problem on the reservation but we have gangs in our cities, if alcohol flows then it can get silly but as Piscolli says there are people camping on mohave point and other areas, set up where there are other people camping.
just an advisory note, they have had some problems with boat trailer thefts and some vehicle breakins just make sure you lock your trailer, (they cut them up for scrap) and sell them!!! and if you have a problem like a theft on the reservation SC PD will not take a report you have to wait for Gila county sheriff to send a deputy out (since you are non tribal) just be smart lock up things and camp where there are others and you should be fine. (good idea to take an older weapon) for self protection.
