My RC club, where I do most of my CL flying, has just survived an attempt by the Oregon parks department to kick us out. They changed their minds -- at least provisionally -- thanks to our lobbying and testimony about how we do, indeed, fit the mission of the Oregon parks (our club VP showing up with his kid the engineering student, who's been flying since he was in diapers seems to have added a lot of help to carrying the day).
Now we're thinking of trying to make that notion stick a bit harder, and to thank the park, by doing some public outreach.
Well, you saved your field and you have it. You could be done right there. I would go no further and let things cool down a bit.
Sometimes, reaching out to the "public" and bringing unneeded "attention" to yourselves, can do more harm/damage than good. I've seen this first hand.
In my R/C days, I've seen three great and one not so great, fling sites get taken away because of nitwits.
And there's plenty of nitwits, wheather you want to talk about them or not.
My questions are -- what's the best way to reach out to scouts and scout masters to let them know about the Boy Scout thing, and what's the best way to reach the general public about the open house?
Like I said, I'd pass on that "open house."
To promote anything, you have to get people/children interested, starting with their parents first.
They see that spinning prop and think that tennis or musical instruments are safer. And they are right. A hurtle?
Realistically. I would suggest getting involved with Genreal Aviation. Start with the local strip, the non towered ones.
Have the event there, well away and unrelated to your flying site.
Or, simply set up tables at your LHS and do a "Model Airplane Day." A show and tell. Then, those interested can be invited to the field. Start small.
You get people into the hobby only one at a time.
And your relationship with your LHS, is the best place where this can start.
