This from the Glasgow 2014 website:
"It is recommended that Spectators coming to the Barry Buddon Shooting Centre plan their journey early as there are significant walking distances to the venue from transport hubs and between ranges. We also advise that you dress appropriately and come prepared as many of the events are outdoors and exposed to the great Scottish summer!
It is not possible to leave Barry Buddon Shooting Centre then re-enter – make sure you bring everything you need for your day out.
Smoking, including electronic cigarettes, is not permitted within any Games venue. This includes any open air space within the venue perimeter. Smoking is discouraged immediately outside venues."
Still. its only shooting and at least the smokers are being demonised as well.
