Hard call to make. Tree limbs that are in the direct vicinity of where the guest are residing in their tents obviously should be regularly inspected and cleared to avoid this type of thing. In this case the tree limb that failed was 50' feet away but it sounds like it caused a domino effect bringing down the fatal limb that killed the youngster. Was it apparent that the weak limb could fall and cause other limbs to come crashing down? It is hard to tell unless we were there to see how things were positioned.

In any case, my heart goes out to the family of this poor little guy. I go camping every now and then and this event will have me thinking carefully about where to place my tent from now on.
