I'd have to say in this day and age a website probably makes the most sense. Most of the ADs now are young and it would be a normal thing from their perspective. If there are some older ADs left they might prefer a flyer and a CD which is what we used to do.
As far as if to start again or not, it is a dilemma for sure. I have some nagging health problems keeping me out now, but ADs are one of the reasons I got out. An example-once an AD asked me if I could setup in a space that was against a wall near a high traffic area (kitchen) and was maybe three feet wide. Fortunately, my wife was with me and she talked to her and worked it out. I just walked away from her. So, I need to remind myself there were reasons I got out. When you are sitting at home doing nothing, it is easy to romanticize the good times (and there were some for sure) and forget the bad. If it was just you and the residents, all would be good.
