You are welcome to either stop by or stay - this is a pretty informal deal and you should feel welcome at any level of participation.
A good number of the folks I have met are still working on their rigs and will show up finished or not. So, if yours is simply a rolling set of beds or nearly complete - you should plan on bringing it up.
Mine is 38 years old and some have even older setups so there is no end of ideas on what/how to do it.
So - for a flyby, the day, or the whole weekend - do come on up!
