Hinting is bad. Guys hate when us women do it because you guys never get it. I have a feeling this is happening in your situation too.

Maybe offer to take them out one more time and then tell them that you'd like to hunt there by yourself for the rest of the season/year/life. Point them to nearest public land to be helpful.

But you have to actually tell them. You can be nice without having to beat around the bush.

That's my .03 cents.
