I believe the Sanitarium was located east and a little north of Springfield and could be reached by taking Rt. 54/Sangamon Avenue east out of town, and then leaving 54 and taking the road that also goes to Camp Butler National Cemetery. The San. and other operations of the church were located fairly close to this change in routes, on the north side of the road - I think. Check with Curtis Mann at the Sangamon Valley Room in the Lincoln Public Library and he can tell you for sure. dmr
