I was at a Ham Radio Meet in Texas City today. OK, for non-Hams, it is like a model railroad show. Busy meet.
But I did NOT see something both Hams and Model Rails need at Public Events and Layouts: A place to sit down, at least for a moment. Most of the time, one is on very hard floor surfaces. That is very hard of one's body even if one is healthy; worse if you are not! Also, a place for families to take a break. I've even noticed malls are placing seating in places OUTSIDE food courts.
Something to consider even if the event does not have a "food court". If you already have this in your plans, THANKS!
