I have lived in the Denbigh area for the better part of 25 years and, until last year, I had no idea this historical landmark was smack-dab in the middle of this neighborhood. I think it can be humbling to know you live in an area with so much history still in tact and bewildering that something like this can be tucked away in this quant little suburb.
The container is a magnetic keyholder and only has room for the log, so make sure you bring a writing implement. Since this an historical site and I didn't want to put anything here that would encourage desecration of the area BUT it is in the middle of a neighborhood and literally inbetween several houses, stealth is certainly required for this one.
Good luck, have fun, and learn a lot!
