The new Sixth Avenue Art Gallery folks were thrilled with their opening night drawing in more than 300 people including, in their words, two past chairs and the current chair of the Tacoma Art Commission, a past city council member, four representatives from the press and other art lovers.  They are open this coming Friday and Saturday from noon to 7 p.m. They wait at 2610-B Sixth Ave., Tacoma.  For more information, call (253) 627-9983. â€" Suzy Stump
