I have to be missing something obvious here.
I've gone through the part were I take the letter off the crate (though its not in my inventory) and I get the nut-butter. I've also pasted the picture of Wallace on the Golf magazine, but after this I am stuck. I've looked at a walkthrough that says I should be able to leave to go back home at this point but it does not let me. I have to be missing something. Any help would be greatly appreciated.
