Tips? Have forgotten some memories of my father (he passed a few years ago) and just want to remember.. Thanks.

Go to places he and you used to go. A few years ago I went the city I grew up in and it was the weirdest experience I've ever had. I can't even do it justice in words, but as I went to my old school, neiborhood, and home I started to have flashbacks like in a movie, only it was like I was there again.
