Does anyone know of any place in or around DW that I could get a balloon filled with helium? We have 2 from previous trips (bought them the day before we flew home. Yeah, poor planning) that I would like to get refilled for our next trip. We are doing the Autotrain this time but it will be a 2 hour ride to get to the station from here and my mom, who's traveling with us, really really doesn't like balloons. I know she would be a good sport about it but I don't want to cause her any anxiety by filling them up here and taking them along.
