In going to the Burlington Mall via back roads today I was driving down Blanchard Road and saw that there's an decent-sized open field along it. The signs say it is the Mary Cummings Estate or Mary Cummings Park. I also saw a sign that says a Burlington R/C airplane club uses it.
Does anyone happen to know if people are allowed to launch model rockets there as individuals, as long as the RC'ers aren't using the field?
