They're not. As you become more familiar with the landscape, you'll find them without much hassle. Sure you'll struggle here and there but don't give in to using a guide.
Honestly, people out there who have used a guide or a youtube video to find them are robbing themselves of a great piece of content.
Indeed Sie. Some of them are really easy, some of them are a pain in the arse, but there's more of a sense of achievement if you do it yourself.
Wiggy, it's actually worth doing as many treasure hunts as you can early on, because not only are they good fun, but the treasure you get sells for a lot of dosh, which can then fund your house/gun/medicine/horse deed purchases.
Yeah sounds like a good way to acclimatise yourself with the map, but as for the first one, i really would know where to start! Will this become apparent and easy to find as i move through the game or is it all about searching the map?
Cheers for your help also Sie
