How may are there? for a couple, two rabbits would be plenty and stick on a spare water bottle just in case.
I have 12, 6 in each and run and have many times left them from a friday to sunday - few rabbits and two bottles on each run.
I see the lads using pins with a loop top, thread the lure line through and the lure takes the pin with it as it hits...less chance of catching a foot on it
