The Santa Lucia Sportsmen's Association
is a great members only club. However, on Wednesday evenings and Sunday mornings they have trap and skeet that is open to the public too - cost a bit more then what members would pay but still very reasonable. They also hold turkey shoots a few times a year which is also open to the public and a lot of fun.
The membership is at a great price and you do not pay each time you go to the range - unless you use the skeet/trap equipment on Wed/Sun. The only negative is that the membership dues are for the calendar year, and are not priced retroactively for new members, so don't join in December I guess
