Tattoo question?

okay well ive been trying to figure out what i want on my tattoo and im not rushing to get it i just want to get a rough draft and its in memory of my grandfather who ped away almost 2 years ago and he was in the Navy and was very into the bald eagle and the flag and i know he liked the footprints in the sand poem and i wanted to have a line from that poem in the tattoo but i didnt know what line to put in it. any suggestions?
