I didn’t see these bears in the tall grass till I was right beside them (8 ft away), Mama still unseen was down in a ditch foraging for whatever. With my close proximity to a pair of cubs, while still in my car. This one stood on his hind legs and called out for mama. Mama came flying up out of the ditch which gave me quite the adrenaline rush even though she made no motion towards me. Then as quickly as I had spotted them all 3 were back in the bush. Taken near elk Lake Ontario with the Canon 50D and 100-400 lens.
