Len Lakofka's L1-The Secret of Bone Hill was another one of my favorite modules. It was because it was solid adventure that was generic enough to be adapted for a variety of campaigns by dressing it up differently.
I thought the map of Restenford was crap. So I fixed it. This an example of my handdrawn town map style
The Map Key corresponds to that of Restenford in L1. You can download the module from WoTC here. You can see by the map where I placed in my Wilderlands. The town of Bernost in the northwest corner of Map 1 (old)/Map 5 (new).
Hope you find this useful if you ever run L1.
