Warm springs can be tough, but it can also be easy...
I have had my very best luck night fishing with big streamers. Something about the sun going down just makes the browns get excited. I have fished right off of I-90 and also downstream where a bridge crosses and then walked up from there. I have also had some decent dry fly fishing during the afternoon, but my most productive nights were fishing streamers. I landed a 22" inch brown at 11:30pm one night...
good luck
