Mystic should be held to higher standard than the RV camps/vacation rentals. They should be held to the same standard as other camps, which afaik, didn't suffer the same losses.
Evidently the death rate was mostly centered on one cabin dangerously close to the river- though they apparently received flood exemptions for others over the years.
No phone policies are common with summer camps. So, that would not have been a Camp Mystic centered policy.
In short, holding them to the same standard as other camps might not change much. For example:
- had other camps also received building exemptions?
- did other camps have no phone policies?
- were the reduced fatalities at other camps due to rigorously practiced evacuation plans- or largely due to luck?
Though I have no idea of whether or not other camps received exemptions, the camps that I am familiar with did not exactly have extensive say, tornado drills.
