If I were pretty new to the hobby (which is a guess on my part due to your post), and looking to expand my horizons, I'd be sure I was good at recovering targets without leaving a trace of having been there (where it matters, such as manicured lawns). One doesn't have to look (read) long to realize that's one of the largest pet-peeves of most MDers because it causes landowners to refuse permission to hunt their properties, and they'll tell their neighbors as well. We've all seen or read about another MDer finding unfilled and butchered-up holes in parks, and other public areas, be sure you're not one of them. So I'd suggest being sure you have mastered the retrieval process 1st.
Without having an idea where you're located, look at old plat maps of your area. Find/read the MDers Code of Ethics (another good starting point if you haven't already. Also, be sure you inform the landowner you'll remove all the trash you dig, and explain that includes sharp cans, metal pieces, broken bottles, and an endless number of items which could damage their mower blades, or bare feet.
