Yeah! Do it, go, have some fun. Some of my best friends are 40- 50- 60, and a lot of them are ABDL. Truth is, us young guards love to know oldguard folks who like what we like. A Great icebreaker if you need one is asking for photos of/with fursuiters! Strike up some light conversation and see where it gets you. Some are more talkitive than others, and that's okay! Then be sure to ask their names and where you may be able to send a copy of the photo (some will assume you mean social media, but personally I always give my email) Often times, that's enough to get you on some fun adventures with new friends ^^ And, if you haven't done a convention before, we can tell if you're crinkly, but some light peekage where you know to share it never hurts!
I'm planning on being there myself, so if you see me say hi!!!!
