i cant believe they limit ya to spikes. wow.
anyway, i think a cow call would still work great. maybe not so much like a hyper hot, but just the ordinary cow call. E.L.K. inc out of Gardiner, Mt. makes a nice little cow call that is really easy to use, and you can just make regular elk sounds like they make year round. i would think a spike would be looking for company. seems to work around here anyway...
that all being said, sometimes it seems like all i find are the spikes anyway
hope that helped at least a bit
