Pass Lake was spent casting and stripping big flies in search of large browns. We have caught browns from mid winter to mid summer and every season in between. Some of our biggest browns were caught in mid winter. A big, heavy, white fly my brother ties, called "The Carpet Bomb", cast to shore and stripped fast is remarkably effective.

I accidentally cutoff Tate's head in this picture. Unfortunately this ended up being one of the biggest browns we have caught on Pass Lake. It stretched more than 28".
