TITLE: Cycling from Bridge of Allan to Blackford

At the weekend I took the train from Edinburgh to Bridge of Allan
and went for a cycle with a friend. We went from Bridge of Allan
along the Sheriffmuir Road to Blackford, a small village along the
A9. Here is an elevation profile and the R code I used to make it:

   # Plotting elevation profile Bridge of Allan to Blackford
   # Data from https://www.doogal.co.uk/RouteElevation.php

   # Packages
   library(ggplot2)

   # Import data
   route <- read.csv("route.csv")
   str(route)

   # Make plot
   ggplot(route, aes(x = distance_km, y = elevation_m)) +
       geom_area(fill = "#4BA8AD", alpha = 0.7) +
       geom_line() +
       theme_bw()

The first part of the route is really steeply uphill, we had to get
off a few times and walk until we got up to Cockburn's Reservoir,
then it flattened off quite a bit.

We got a load of geocaches along the way, about 14 I think in
total, including one in the park in Bridge of Allan.

It was really interesting seeing the old larch trees up on the
tops, which I guess are remenant of when there was a lot more
forest on the hills, before grazing pressure increased, now there
isn't much regrowth and it looks like in about 50 years there might
not be any trees at all on the tops, except for some areas where
there is plantation forestry.

The raised bog had loads of mushrooms, especially in areas that had
been recently disturbed by a tussock being pushed over, or a rut
caused by a tire track.

There were also lots of caterpillars, though I don't know what
species they were.

We got talking to a historian and amateur metal-detectorist who
showed us some WWII bunkers that he reckoned had been used for
testing different types of explosives on concrete, then had been
repurposed as training grounds in later years.
