So, I'm a grouchy, mostly solitary old geezer who'd rather think than fight, and who spends a lot of time wandering the wilderness, am I?
Er... yes. But I refuse to grow a long beard and wear a pointy hat on a daily basis.

Update: Hey, I wonder how much it'd cost to get a proper wizard's tower built in Dogpatch. Not that Gandalf ever had a tower, mind you. Hmmm... needs stone, mortar, and labor, plus some civil engineering (AKA target design). Just another thing to ponder.
