Took off from the house on the mountain bike.... was going to go do a 3 or 4 loops in the small state forest trail near by. I thought somebody in the neighborhood was burning leaves or something. But I got about 3 miles from the house and there was still smoke everyplace. Did almost a loop on the trail and was blocked by 3 or 4 trees over the trail (no way around them this time really). So turned around rode the trail back the other way. On the way back I scared the tar out of a girl and her friend walking. I said "honk honk" and she about jumped out of her skin. Honestly though This part of the trail is just covered with dry leaves and twigs, I mean I sounded like a freight train coming .... I have NO clue how she could not hear me.... LOL.... They laughed though.... By the time I got back out to the entrance to the trail my throat was kind of burning.. So just took it easy back to the house. Ended up riding about 56 minutes... 9 miles I think...
