From what I have heard (and this information could be entirely wrong) but the only time you could shoot at Danvers was if a Range Safety Officer was present. And when the discussion continued, I came to find out that range safety officers are not there all that often, something like 10-2 M-F. I could be totally wrong, but I would definitely look into it before joining.
I went down the street to Hamilton Wenham Rod and Gun Club and have never looked back. Daylight access to the shooting ranges, 25m pistol range, 100m rifle range, archery range, catch and release pond stocked with trout, and trap shooting with other club members Sunday and Wednesday mornings. If you take your initiation at the shotgun range, you get total access to one of the traps to use when you please.
Every guy I have met there has been very nice, accommodating and very good natured. I highly recommend the club.
