As I see it, it's really pretty simple: If the Commonwealth of PA has restrictions in place that the TCA-ED and Expo Center must adhere to (pretty unlikely for October at this point), you follow those restrictions. If there are no restrictions and you are fully vaccinated (I am), you go about visiting the meet as you normally would. If you have chosen not to be vaccinated, you can either wear a mask (nothing wrong with that if it makes you feel comfortable), or don't wear a mask/don't social distance/etc. and take your chances. All life is a gamble, and it is never risk-free. At my advanced age, I plan to do my best to live my remaining years as free, healthy, and happy as I can possibly make them. I hope to see you all at York!
