State College has some + and - factors for running.
+ There are lots of trails (google Rothrock State Forest).
- there are a LOT of deer hunters (hunting season lasts a few months in the late fall)
- deer flies awful in July/August
+ it is never as hot as Phoenix
- it is often 90F and 90% humidity in July/August
- it is often 32 F during the day. 32F = slush. something you've never experienced in Az.
slush sucks. freezing rain: as an AZ driver, you will have a car wreck in year 1. don't buy a new car with your first paycheck. get a Suburu beater with airbags.
+ awesome fall foliage
- very grey in winter, all the leaves fall off
+ several tracks to choose from
- not sure if they are still open to the public.
If you are 21, then there are lots of single, drunk, horny people your age.
since you are 25, then you better like to date grad students.
