You can simply talk to someone involved in the program, someone who's taking pledges and sleeping out, or one of the teams and give them your pledge. (We can even bill you later if you want.)
You can send a check (payable to Siouxland Sleep Out) to Mental Health Association, 2003 Geneva Street, Sioux City, IA 51103. If you're supporting someone who's sleeping out in the park be sure to mention their name when you send the check in. NOTE: Checks must be in the mail by Oct. 30, 2010.
