I wanted to show this, as IMHO, this is just the tip of the iceberg.

As the population continues to grow, land for flying, and other activities, will continue to get scarce, leading to the ultimate reduction, or even the demise, of our activities.
As an example, I live in Northern NJ and have to drive 1 1/2 to PA to fly because there are no fields closer that support the type of models I fly, and I'm sure there are other metropolitan areas where this is a problem too. The days of going to the field to fly after work are gone, at least for me.
I'm curious what the hobby will be in 10 years time.
Maybe in the future the only thing you will be able to fly will be the $20 WallMart PF, and if so, what a shame that the hobby devolved into that.
BRG,
