Time off, till I retire in 18 months, is pretty well spoken for, but, I'd make every effort to attend one of these, if the time is right. For me and my work, I'd need several months advance to put in for the time off.
I think its' a great idea though.
Mac,
Where's here?
We have a range here (soCal) that goes to 600yds that hosts a lot of this type event with room for dry camping, but I'm clear out on the left coast.
