I have a stack of maps my grandpa used to plan fishing trips with his buddies. How I wished they would have just marked some spots down! Taken some notes in the margins!
Every hunting season I tell myself I should start journaling my hunts. I have a group of friends I get out with a few times a year for a kayak, canoe, or hiking trip as well. I think starting this summer it would be nice to start journaling about trips and hunts throughput the year, details of where I was, what I enjoyed, etc, so that hopefully someday my kids or grandkids could have a feel for the things and spaces I was most passionate about. Maybe even be able to re-create a trip or two if they wanted.
I have some of grandpa's fishing stuff and a hunting knife, they get used from time to time just for some connection to him. It would be fun to be able to go back to see the places he enjoyed on those trips though. I tend to buy good gear, so I should have things that my kids will be able to use if they want to. But I want a way for them to experience the places I loved after I'm gone, a way to see them through my eyes.
