I have set up right in the middle of towns before , their not real smart critters .
Time between shots depends on the amount of dogs , air temp , sunny or overcast , I've had 3 rifles cooling while shooting the forth there were so many to shoot at .
As for how long they stay down depends on how often their shot at , if once or twice a year , they come up fairly quickly , if they have been shot at alot , it could be awile .
They tend to go underground during the heat of the afternoon , just like us , they don't like too much heat .
