I believe that his Excellency makes some very special points. I would like to add one more. Bringing the history back involves more the physical environment It also involves the social environment. Even if you are not into History and you are living the Dream or Living the SCA or view the SCA as path to a better you, working on making our physical and social environment more historical will make your experience in the SCA better. When we drift to the mundane we shift our thinking away from the ideas were are studying. Honor, chivalry and courtesy become replaced by the relative thinking of the modern world. The more real we make our world the stronger the values of our world. 
I was thinking of making a flyer and putting it on cars and mundane stuff. Of Course that would be rude so I probably will not do it.
Here is my flyer. What do you think about it? 
Do you love Ansteorra? Do you love the Dream? Do you think the SCA is a place of high ideals? Then I would ask you these questions?
Where is your car? Is it hidden in the parking lot or is it a big fat reminder of the modern world out in the open?
What does your camp look like? Are soda bottles and mundane bags put up? Is your ice chest covered? Do you have a little bag on your Gatorade bottle? Is your mundane chair covered? Have you made an attempt to decorate with banners and things?
What do you look like? Are you wearing tennis shoes or blue jeans? Are you wearing a T-shirt where people can see it? Is your watch in the open? Are you carrying your phone in the open? Do you have your drink in a proper tankard? Are you carrying around a plastic notebook? Are you wearing a costume that is neon or tied dyed or has cartoon characters on it? Are you wearing something that screams the everyday world?
How is your behavior? Are you taking phone calls in the open? Are you talking about your computer? Are you calling everyone by their mundane names? 
Have you been trying to make Ansteorra and the Dream real? Have you been using peoples titles and SCA names? Are you having conversations about history, the SCA or your persona? As a Lord or Lady of Ansteorra, even if you don't have an award, are you modeling the proper behavior that you want the new members to do? Have you taught the new people about what a true peer or noble should be doing? You never know who will the next king or peer. 
Are you and your group the kind of people and doing the kind of things that should be repeated over and over again by the new people? We make up the  Dream! We make up the Kingdom! Each one of us need to support making our SCA world feel real. You might not realize this but the general populace has more affect on the newcomers than the nobles and peers. They look to you as the models. We need to all make an effect. It doesn't need to big, like having a period pavilion and hand sewed clothes. It can be small. Put up the mundane and don't talk about the everyday world and show respect to people's personas. Put up a banner. Give out a favor. Address someone with their new title. Have some forsoothly small talk. Flirt with someone in a Courtly way. If we all make a little effort big things will happen. 
Thank you for listening
