A few years ago while at a GLBTQQIA meeting I listened to a young person relate an experience where she was in near-crisis internally while coming out, feeling very alone, etc., and one day she happened to see a rainbow flag flying from a house near her school. She said she never knew who lived in the house the entire time she was in school but she somehow felt safer knowing someone who would understand her was nearby. I left the meeting, found the biggest rainbow flag I could on-line, and have had it waving off the front of the house ever since. I've met so many folks because of that flag.
I added a single sticker to every vehicle I own, including the two-wheeled ones. I have traveled just about every road in the US and Canada (seriously) and have NEVER had a single issue. Well, that's if you don't count the plethora of times I've passed a vehicle on my bike only to have the same vehicle speed back up and nearly run me off the road as all the same-sex occupants energetically waved, saluted, honked, thumbs-up, etc.
