I can understand that.
Although I haven't ice climbed in years (it's undoubtedly more crowded these days), my solution to crowds has always been simple.
Get there first.
I remember one of the times I climbed Repentence, you could drive on the road almost right below the climb. Got there in the dark with no other cars in sight, and just knew that we were gonna get to the base first. So we (I honestly can't remember who I was with) nonchalantly geared up and strolled up the trail. We were only there only a minute or so when two climbers came towards us- not on the approach trail, but rather along the base-of-the-cliff trail. Turns out it was Jerry Handren and a client from IMCS. The sneaky brit almost beat me to it! He told me he had used this tactic many times.
