Basic snare question

[GSP x2]

Ok like I said just started doing this. Have another question. I have been setting snares on runs and having some easy catches. Now we had our first snow yesterday in Iowa. I went out looking for tracks. I noticed they were all over not so much on the runs. I want to take some of these animals. There is no real pattern to them just all over. Mixed bag of tracks FOX COYOTE COON. Can you guys help me think of how to set snares or 220's to catch them. I took your advise about loading an area with snares and it works for sure.
Part two. I have my snares blended in pretty good or at least I think so. I watch my scent very good. With this last snow I have noticed some coon tracks around my snares not in them. Any idea on how to stop this and get them to run into my set?
Any help would be great
Thanks and happy holidays
