Note: It's actually "Hallows" Eve, not Hollows.
Bill is an absolute badass... his work is present all over this county, and all of the folks who have been blessed with his art all sing his praises. Many of them have stated that they will not let anyone else touch them, only Bill.
I have one large tattoo from Aaron at Hallows Eve, and I always get complimented on it wherever I go. The color "pops" dramatically, and the detail is first-rate. My wife had a piercing done there, and the person performing it was very good with her, as nervous as she was at the time.
Bill and staff are very personable, knowledgeable, and patient.
