Love the name!
You know, my BP never uses his half log either. But then again he has 4 hides to choose from so maybe its just his least favorite.
Not sure about the white spots. Hopefully someone else will answer. If noone does, you may want to create another post on the subject so that it is at the top of the forum and people are more likely to see it. If you have pics of the spots to post, and people will most likely ask about the parameters of your tank - as I said before many illnesses in snakes can someone be traced back to improper husbandry. So make sure you have the 2 hides, the right temps (90warm side, 80-85 cool side), proper substrate and are measuring humidity and temperature correctly, etc.
