The first thing we need to do for our own PR is talk up modeling when ever you can. Modeling is a solitary hobby mostly done by yourself in your hobby room so a Society like IPMS/USA is a great way to make new friends and meet people with like interests.
My own experience came over 33 years ago when I joined my local club and was the only automotive modeler in the group. Took some time to get in with the group but I helped myself by inviting other automotive modelers I met along the way - 6 to 8. Some stayed and some left rather quickly and life took it toll also.
PR is up to all of us and we have a harder time now than ever before due to the need for instant gratification that seems to be the norm today. Having recently moved to Hawaii, I was invited to an neighbor's BBQ to meet families in our neighborhood. During a conversation on history I asked the neighbor if he built models and found out the he and his oldest son had just begun doing just that. So I offered to be a resource for questions. That is how PR should be done - get out and ask.
Have a nice day and build a model.
