Why not start a new thread with THAT question written? Seems a good question if its a true concern, but you said it, it has nothing to do with (this) Temecula match at all.
That said, I already hosted a match with "lane pods" (a pod of lanes with a large canopy and up to four shooters firing on different lanes. Some areas available had the ability to safely have shooters firing nearly "back to back" to allow cover in case of rain, yet minimise walking distance a bit.
The intent was to give cover and shade, and short of tht, there is little benefit I guess.
