Sorry to hear about your dad, I lost mine in February I know how you feel it's awkward.
I decided to go out this year and take his Ruger MKii .308.
Then passing the tradition on to my son and daughter when they get old enough.

Just going out brings back the memories, the best one was going spring turkey hunting for the first time and we wore our blaze orange hunting suits lol seen more dam turkeys that day.

Hope you can get out and enjoy the PA woods.
