Demographics change across the country, I doubt there are many "rogue" flyers in the greater Toronto area, the only places large enough to be RC friendly tend to be the handful of RC fields in the area.... Park flying or line control on the other hand, that's a whole different matter....

As for recruiting existing modellers, I have direct experience as I was one of the founding members of the Huntsville Model club around 1974 I believe. Increasing membership is a noble cause, and I think providing a stable, available and effective training program is much more key to this cause. Something my home club (Ajax) has done, and continues to do quite well. Unfortunately, not all clubs (in fact, I would have to say a majority) are keen on training or even hosting newbies. You may know Clarence Ragland as he is well known for espoucing his views on this, I happen to agree with him, and use his Instruction technique, after witnessing how successful his approach (Ragland method; basically Kinesthetic learning) is. This is something I think most clubs serious about recruiting (and instruction) should evaluate.
