Hi, Mike.
You can keep my small donation because I know you and your family personally. I know the alleged abuser, too. I know that you aren't trying to "con" anyone. People obviously will think that you are "running a hustle" because they were primarily donating to help get you to the march.
Simon, Pennsylvania state law requires an "in-person" testimony from the victim(s). They won't accept videotape testimony from out-of-state.
Mike, I hope you can still make it to Pennsylvania.
Brian
