'non viability' of a club observatory.
The drawbacks out weighed the benifits as far as we could tell.
We did however think an 'observing grounds' with concrete area
and telescope pillars was a good idea.
Something along these lines:

The benifits are huge.
A solid ground.
Piers pre set so all you need bring is your OTA.
(no lugging tripods)
Groundings could be set in the concrete around a pier for
removable wind breakers.
safe observing / no tripping over or bumping into others gear.
The list go's on...
