they are not open to the public but you can ask someone who is a member to bring you over as a guest. i would offer myself but my weekends are planned out two month in advance unfortunately. summer is busy time in my family. i will let you know if opportunity opens up if you are still interested at that moment.
there is a thread dedicated to Ames club somewhere on here. you can find members there maybe repost your call for a range trip, i'm sure someone will come along
