Five Things: Oct. 24, 2011

1. Nominations are being accepted for Arlington's 2012 Notable Trees. Notable trees must have some unique characteristic about them. Winners will be placed on the county's notable tree registry, which can be used by civic associations and walking tours. The county does not have any authority over trees on private property. Nomination deadline is Dec. 15.

2. The Arlington Public Library has a new collection of more than 650 Disney Digitial eBooks.

3. Dogma Bakery in Shirlington is hosting a trick-or-treat with your pup event from 6 to 7:30 p.m. Saturday. After filling up your bag with pet treats, the business will feature contests, photos and more.

4. Remember, it's $1 Mondays at Arlington Cinema and Drafthouse!

5. The Sun Gazette looks at diversity in Arlington's schools -- and among its teachers, not just its students. In the school system, 74 percent of the teachers are white while only 7 percent are Hispanic. That compares to a student body that's 46 percent white and 28 percent Hispanic.
