Seems I have had better luck callin' in multiples in April/May when they are start to group up for the yote rut. Last year near Moses Lake I set up downwind of a large bowl and let 'er rip and in about 30 seconds had 5 runnin' in tryin' to be his pal to the wounded rabbit. They all went past me at about 40-50 yards still runnin but there was only 4 left thanks to the 22-250!!!!!
Get groups of 2 or maybe three earlier in the winter but lots of singles that time of the year.
Have to work a little harder now to find spots that they are not call shy with the popularity of this now. These are still some of the best times to spent with kids. They love it and get 'bit by the bug' when they see one coming in.
Bobcats, ya lots of them too here on the westside. Pretty easy to call in!
