There are several range masters on the rifle range. Some of them are not super social, and all of them are militant on the enforcement of range rules (which can be a bit restrictive). But if you follow the rules, all is good. If you don't know the rules of any range when you walk on the grounds, it is best to ask in advance so there are no surprises. I was on one range over on the Kitsap where a guy fired down range during a cease fire!! That guy would have been banned forever from Kenmore, but was only given a warning at the other range I was at!
One thing to consider which makes Kenmore a bit different than other ranges is that it is basically in the middle of several neighborhoods and many of the neighbors would love nothing more than to have a reason to shut the range down. Any reason. Injuries, shooting too early, shooting too late, etc. They get calls about automatic fire on the range all the time (and automatic fire never occurs... just reported as such by ignorant/trouble making people.)
It is always shocking to me that people buy a house next to a gun range and then complain about the gun range. that range has been there long before any of the houses. It is like buying a house next to an airport and then complaining about all the dang planes flying around...
Membership fees get you free access (except for targets which are 50 cents each) to the rifle range as well as the archery courses and pistol range. Shotgun range is still fee based, but you get discounts on shells and trap/5 stand rounds.
I have been a member for 3 years. I have paid for the membership several times over in that time. If I were the kind of person who shoots 2-5 times a year, then it would not be worth the money. Given the amount I shoot, It has been a real money saver. Everyone has their own cost case to consider.
The rules are pretty restrictive, but it is a very safe range in a heavily populated area.
