Tomorrow, this 73 yo will do some mtn biking. I have gone over that slow leaking rear wheel with a fine toothed comb and can not find the cause of the slow, small leak, except possibly the small remnant of a goathead. So, I put in a new tube, pumped to 60,and will check the tire first thing in the morning. Hoping for the best.
I will go to either Spruce Mountain or Spruce Meadows Trail - some of our open space in Douglas County, Colorado. I did Spruce Meadows last year - it is where the Sheriff stopped me for being too close to the railraod on private property. I showed him the map and he agreed. They have changed the map this year!!
Spruce Mountain is by far the tougher for me. I need to leave about 5:30 am to avoid the heat.
Here is a link to Spruce Mountain
Here are maps of each - click on the next showing map for a very enlarged view.
