I agree with the 2 posters referencing a "select" group of individuals the "mortals" and the "good old boys". That "good old boy"network is tough to crack at the MRA... I think I had to actually sit down and introduce myself on a Sunday Am to some of the guys hanging around.
I can only assume the by "select" folks they are referencing the BOD and folks who seem to be permanent fixtures at the MRA. From my observation they also seem to be the ones doing the bulk of the work and day to day management of the club. There are also provisions to become a member of the BOD. If you do not like the way things are run you can always run for a board position and change them.
The MRA is what it is and your experience will be what you make it. You can come during hrs that the club is not open and members are not hanging around and be left alone. You can come when there are members everywhere and be left alone. You can also engage members and easily make friends.
I have been a member for around 5-7 years now. The first 5 years I came in and did my thing and left. Then I started coming to different events and helping out where I could. Now I know most of the "select" members. On many occasions I have met other members as we have fixed target runners, swept and taken out trash first, instead of shooting, as it needed to be done.
To the OP do not discount the MRA. I believe it is the best club around and it takes me around 30-40 min each way to commute. You can make the experience what you want it to be. Obey the rules (which seem reasonable for the most part given the location) and then make the experience what you want it to be good or bad.
If you want to check it out then there is:
Wed night trap: 5:30-8:30PM
Sun AM Sporting Clays: 9:45AM with 10:00 start-12-1 PM (don't have a shotgun use mine or the club gun)
Sun afternoon : Action Shooting Plate and the occasional savage bowling pin.
Summer is coming and there will be different rifle matches (some for club members others that are open I believe) Check the MRA web site for more details.
Good luck in your search.
