We've still got late spring conditons, and the temperature is supposed to range from 57 to 78 degrees and there is a chance of thunderstorms, according to current weekend weather forecast for Pennsylvania at a point near the Appalachian Trail..

For the next four months, this sort of weather, or warmer conditions, are expected to prevail on most of the AT.

When walking, it's possible to slip and fall. In doing so, it's possible to break bones or dislocate joints. Experience and training in walking can increase safety, and some people OUGHT NOT CHEW GUM while attempting this.

One can die of sleep apnea, a condition that results in excessive snoring. Medical training and years of experience can be helpful in diagnosing this condition.

Obviously, one could also be hit by lightning.. Advanced physics (are?) required to fully understand the dynamics of the situation. This requires at least several years of training at the university level. Fortunately, flash floods of the sort found in desert canyons don't occur in this region, so additional hydrological training is unnecessary for safety.

Getting more than a couple of miles from a paved road is rare to impossible in this region. There are no dangerous wild animals.

Cliffs or rock ledges in Pennsylvania are rare. Training, preferably from a certified instructor, can help one recognize dangerous terrain. Years of experience in this immediate region would be less helpful, because there isn't any dangerous terrain.

Swimming is quite dangerous, and for this reason, very wise and experienced authorities have carefully banned this activity, unless a trained and certified lifeguard is in attendance. Otherwise, DO NOT ATTEMPT THIS ACTIVITY. Read all rules. You may endanger yourself as well as highly experienced rescue personnel, who have families, and much better things to do with their time than become part of a tragedy caused by arrogant foolishness and inexperience.

The crime rate on the trail is very low, although Penn State offers helpful instruction in criminology provided by Ph.D recipients, and police and other public safety authorities can be made available for a free consultation, IF you know how to contact them.

Fire is also dangerous. You can be burned. This may be painful, and has resulted in unnecessary fatalities. My girl friend has difficulty operating a cigarette lighter, but fortunately, I've had lots of experience, although no actual training.

Be safe.
