You can bet that the coming weekend will see the herds blindly stampede to Lillooet despite great climbing on offer in other parts of SWBC if it stays cold.
There is nothing to fear from herds. Unless you too have herd mentality. No one ever goes to Hell Creek, Spray Creek, Cedarvale Falls etc because they are too busy swarming to the Rambles and Marble Canyon. Hell even I climbed at Marble and Rambles last weekend.
