(Marlon Correa)

Friday’s the deadline for entries to the Loop’s contest to figure out where Congress should put that East Coast missile defense site. A really good suggestion may induce the Senate to agree with the House’s proposal to protect us — now that the Nationals are finally winning — from Iran’s potential long-range missiles.

You can leave your entry as a comment on the blog — you may want to double-check that there’s an active e-mail address associated with your washingtonpost.com log-in.

You can also e-mail us at intheloop@washpost.com. (Please make sure you include a home or cellphone number so we can contact you.)

The top five winners will receive a coveted In the Loop T-shirt and the usual bragging rights when we announce winners. (If you need to enter “on background,” that’s fine.)

Good luck.
