And likewise, it's refreshing to have pilots visit the tower (or ARTCC/TRACON) to see what's going on on our end.
As a student pilot, my 'class' (the instructor and one other student) just recently did a field trip to the tower at our local class C (KBIL). It was actually quite edifying. As I progress as a student and later as a pilot, I hope to continue such visits as a routine (possibly even once a quarter, assuming local management is amenable) to stay 'in tune' with the local controllers and issues.
