El Haggis

Hi people. I don't know where to go to ask for help, so I'm just going to ask here. I found a cache yesterday, noticed it completely by accident while picking up my dogs leavings. Stupid me picked it up without properly looking through it until i got home. Unfortunately, I don't actually own a GPS, so i can't play, but i would like to put it back for other people to find. I'm pretty sure i remember where it was , but I'm not entirely positive. What should i do?
