The usage fee of $25 gives you (the member) unlimited use of those two ranges for the year. If someone doesn't want to pay the $25 unlimited, then they can pay $3 per use of the two ranges. Definetely better to pay $25. Any visitor that you bring with you has to pay $3 for use of the range in addition. Not a bad charge for the facility. The shotgun ranges generate revenue for themselves by charging "I think" $3.00 per round.
To become a member, myself or 00bullitt will have to sponsor you and you pay your dues for the year. You then get voted in and become a probationary member for six months. After six months, they will bring you up for vote as a regular member (you can vote and sponsor then). Nothing to it, just don't piss anyone off for six months. Rarely will you find anyone there when you go to shoot. Wednesday evenings are the "cookout" night. Members come to shoot skeet and they cook for like $6 a head to generate more money for the club. 4th Saturday morning of each month has the IDPA local shoot on the pistol range. Other than those that I know of, show up daylight till 9:00pm and the ranges are your's.
If you'd like to get to work on becoming a member, let me know and I'll get the sponsorship stuff together and get you in. Just send me an IM with contact info and I'll help to get you started.
