Thanks for the tips, they don't seem aggressive at all, just very interested in food and water. I've started to have fun watching them. They seem to know when I have food out and, interestingly enough, are not interested in beer. I need to go out later for batteries and will get a can or two of Mt Dew as suggested.

Am 2.5 hours into a mtb trail hike, was pruning sticker vines along the way which slowed me down. I've a couple more hours to go then will test my mtb bike again after fueling my body. I AM feeling better each day, but no mountain biking until I can be in that position without pain. I figure that physical discomfort, even if just bruised muscles, can contribute.to a fall.
