I wouldn't have thought a reflector would last very long. Especially now we are only allowed the one communal fire. Who would want to sit behind it?
Having large logs around the fire - another one I'm a little down on. Great during dry weather, but wet in the rain. I think everyone bringing something to sit on around the fire is a better idea.
You could enclose the seating are with logs though, just as long as you need enough room to move away from the fire should Bernie be managing it.
