I train new comers from time to time. A good comment came up about wishing more sets could be made, but time is limited before school, etc. There is an answer to this. (you may spend more time after school or in the evening skinning). But that is a good thing!
Make sets, FOX for example, in locations that CAN BE SEEN from a distance & CHECKED WITH BINOCULARS. Saves lots of walking time. Every few days walk to set to make sure trap is not exposed, re-lure, etc.
For COON sets especially, a FLAG STICK can be set up at set area. Works great if checking from road near culverts, bridges, etc. If flag stick is down you know you have a catch. Travel on if flag stick is still up.
To make flag stick, get stick, branch, etc & tie a flagging ribbon to top end (can use no ribbon also).
Make your set on creek (or wherever). To save time set has to be visible from road or path. Lean flag stick next to set against bank or a tree so visible while checking at a distance. Now tie cord or wire to bottom of standing flag stick to trap chain, or just loop trap chain around bottom of flag stick if that close to set. Caught animal will knock over stick showing you have a catch. If using large drag you can just stand that up that against bank or tree.
Hope this creates a bigger line for ya
