Naah chances keep improving: As Thor sells more the probability that you see another one goes up. (Granted the chances that you pull in at the same exact time lowers it a little but still...there are a few of us around--I'm counting both Axis/Vegas units)
Some examples from the same trip:
In the first instance we talked to the owner who is on here (neither of us had any idea that the campground would put us next to each other), in the 2nd instance we didn't see anyone to talk to.
er. not trying to have a negative tone...just pointing out that it happens more frequently than you may think...
