Have you guys heard of this? Apparently it's been happening for the last two years, but this is the first time I've caught wind of the local pseudo-holiday phenomenon known as Hallowang.

For some, the fact that Oct. 31 comes only but once a year is simply not enough. Like the set that enjoys celebrating half-birthdays, the proprietors of Hallowang have selected the last weekend in April to celebrate Halloween's half birthday.

Here's the deal:

According to the holiday's creator, known affectionately as "Housecat," anyone with a little springtime costume ingenuity is encouraged hit the East Side streets tomorrow, Saturday, April 26, for a little Hallowang bar-hopping. (What else?)

Beginning at 7 p.m., Cans, Yield, Vitucci's, Y Not 3, The Eastsider and LIVE have discounts going on for the costume clad. And of course, there's a friendly costume contest for six categories: Famous people (dead or alive), stereotypes & occupations, fictional characters (traditional or original), non-human, team and spectacular.

Here, why don't I just let the Web site explain the rest?
