Why are Li Ion UPSs so expensive?

'Average' 10%.

The 7% is for the benefit of semis and aging RVs. At 10% many passenger cars will need to downshift.

I've been to Pittsburg but not in the winter. I imaging the locals avoid it. It was nowhere that steep but there's a grade near Holyoke Massachusetts with a stop sign at the bottom. After the first snow the TV station would send a cameraman out to record the antics. It was reminiscent of those clips of gooney bird landings.

The average angle from where the path starts zigzagging (zoom out to satellite to see) to the peak of Ben Nevis is 24 degrees from horizontal, which isn't that steep, it's less than the 2 o'clock position on a wall clock. I worked it out by measuring the distance of the path and the altitude ascended using Google Earth. Inverse tangent (altitude gained / horizontal distance) = average angle of ascent. A pretty easy path, I've done it barefoot. It's not like you need walking poles or crampons. In fact I was overtaken by someone running up it! More surprising was when he ran back down and I had to step to the side rather quickly. I don't believe he had full braking ability.

Since you guys all use autos, who cares?

There's a motorway near here where I have to drop to second top gear to avoid falling below 75mph. That was in a 1.3 litre Rover Maestro, and a 1.6 litre Renault Scenic, neither with much weight in them.

The funniest thing to watch is dustcarts on ice. Since they come out early in the morning, it's seldom gritted.

In the last 10 years or so they've been closing some of my favorite cardiac arrest trails for 'restoration' and building graded trails with switchbacks that are three times as long. I'm not anti-biker but I think it's in part from the bicycle traffic increasing erosion.

Probably a good thing. I grew up back east where the trails mostly went straight up the mountain and had be used for a couple of hundred years. Most of them resembled dry creek beds except in the spring where they turned into creeks.

If you want to post hole through 3 miles of rotten spring snow, more power to you. I'm too old for that s*it. It was more of an exploratory trip to see how bad the fire had been and I didn't bring my snowshoes. THe good news was the upslope hadn't burned although the canyon was gutted, including several houses. People insist on building in the woods.

I'm a cyclist myself, and in Scotland we have the right to go anywhere you can go to walk, which is also anywhere. There are no restrictions on any foot, cycle, swim, or canoe travel. And you can do it naked.

Snowshoes are for girls.

I prefer touring in a canoe. Like with a bicycle, it's a vehicle for travelling and enjoying scenery, not for performing tricks.

Some of the hiking trails are designated for foot or horse traffic only. Also a bicycle is a mechanical device so areas with a wilderness designation are out.

The new switch backed trails take all the fun out of it. There is one trail that looks like a nice loop if you're not looking at a topo. Up Spring Creek, over to Rattlesnake Creek, and back to the trailhead. The fly in the ointment is Strawberry Ridge. Before the new trail it was straight up one side and down the other.

Whenever hiking or camping, I've always quickly gone off official people trails and follow an animal trail. Takes you where few others go and get to see.

I'm not good at coloring between the lines either. There are places where leaving the trail is painful and I avoid those. Deer trails are good. They can be steep but deer aren't mountain goats and aren't going to lead me off a cliff. I do wish they were a little taller though. Bears are even worse with their 3. high tunnels through heavy vegetation.

What was the battery doing when producing the gas? Was he deliberately overcharging it?
