Probably 45-60 minutes for a drive; depends on the traffic as to how far that is. 

I'm lazy....45 minutes....

60 miles one way.

We went to Santa Fe for a meetup many moons ago.  

4 hours any direction and where I'm located that will cover 4 states

The time for the travel and the convenience of the location may be more important than the miles. 

Some urban locations lack free and easy parking which may be a consideration.

Never attended one.

We have driven as far as Tucson - which was just over a couple of hours away...

Depends on what I have going on for the day, I'd probably cap it at 2 hours if I could.  Although, here in southern CA, that could be just a few miles ; )

I live in an extremely rural area. I have driven about 160 or so miles and it was mountain driving. It took me about three hours. 

We usually have them in Denver, and within 45 minutes.

Raymond, maybe an hour.  I did drive three hours to those RainCamps that they sponsored and that was well worth the drive and fighting Chicago rush hour traffic!

We are driving an hour plus for the meet up we are hosting in Santa Monica.  Other than us, there are not many active members on AR from our area.  We love going to LA once in a while.  A

I'd fly to a neighbor island in Hawaii or drive anywhere here on Kauai.

It would be an hour for me ....

90 miles, that should just about cover any area around Denver that would have a meetup, although if Hawaii is having one I may make an acception

I would say an 1 hour.  But in the Metro Atlanta area you drive 1 hour to every where.

I have traveled 90 minutes and would do it again.

Is the food any good? 30 miles.
