RE: Fly alone?
Well gee, I joined a club so I could fly with other model enthusiasts. Except for a few rare occasions, it really isn't that crowded when I go to our field (most crowds are on the weekends). Last week we had a low key event with lunch provided. About 20-25 people there but you never had to wait for any length of time to get a flying station. No one was on my frequency either but we still followed field rules. Last year I had a 3/36 job which ran Sat/Sun/Mon. I had the rest of the week to fly and virtually no one else flew on weekdays. I got lots of flying in but it got kinda boring.
I also fly a good deal of control line where you have to launch from a stooge while flying alone. Every control liner will tell you NEVER to fly alone. The risk of getting seriously injured with no one to assist you is just too great. Besides, flying and shooting the bull with your comrades is priceless.
Our former CL field was restricted to only Sundays and Wednesday evenings. This resulted in 6-10 folks being there at any given time in those slots. We all had great comraderie. Now we can fly unlimited and I rarely find more than 1 or 2 other people there.
I enjoy the best of all worlds and fly with my 15 year old son. He rarely misses a chance to go flying. I suppose in another year or two that may change but he's a great flying partner and can outfly me both in CL and RC.
