My outdoor growing situation

Just wanted to get some overall thoughts on an outdoor growing situation.
I have some family property about 20 miles outside of town located in the mountains of eastern Oregon. This is the perfect spot to grow, I think.
It is located 20 miles out of town, no one goes up there in my family, no one would be able to see it from the roads, at all. And it's far enough away from the next piece of property that no one would smell anything either.
I want to try and grow some plants up there but I'm not able to get up there all that often. How successful would I be if I just put some plants in the ground and checked on them about once a week or every other week? I know this is not optimal attention they deserve, but it's the best I can do. I also dont really want to waste good seeds on a project like this. I would rather just get a handful of common seeds and see what happens in a few months.
Any ideas about the location itself and or growing situation would be greatly appreciated.

Thanks, Kayas

There is a water source on the property that should help growing nicely.
Can I expect a decent plant with very little attention though? The land is nice and near a water source and it will get lot's of sun light and plenty of rain in this area too.
I'm just trying to avoid going up there as much as possible to keep suspicion down to a minimum. But like I said no one would ever see me going up there really.
