Some things your gonna want to understand, maps wont be able to tell you very much with out boots otg.
I like to think long term, like scouting is an investment for my future seasons, so Is this a property you will have a few years to hunt? If so, summer trail cameras may not give you a whole lot of useful info, they could but probably wont. Get your cameras running through the season. This will give you ideas of where the travel/cruising corridors are. Then you adjust fire for the next season.
If you are able, take the time to walk every Inch of the property. This could take sometime but 100acres you should know everything you absolutely can about the property.
While learning the property by walking it, look for transitions, edge, tkey terrain features and sign. If you get out there now and burn it out right now, itll have time to settle down again prior to hunting, get in there asap, as your best time to get in there has passed (being winter post season)....
Move slow, observe everything, take notes and pictures, use onX itll give you a great baseline to start building off of.
