Does PA require a course to obtain a hunting license?
For junior hunters, yes.
I believe that once you are 18, they do not require you to have it. You can just show up with a driver's license and purchase one.
On your other post, we also fill out an additional form whenever someone purchases a handgun (one form for each pistol). We call it the PSP (PA State Police) form as it is sent to them after the sale.
