Today I tried drilling a hole in the guardrail - but the drill bit
wouldn't make a dent.

What would you use to drill a hole suitable for mounting a garbage can
where there is no electricity available?

Center punch a starter point, and hit it HARD. Make a hole with a small
(less than 1/4") bit. Graduate up from there in size. Don't overspin the
bit. As long as you are getting cuttings, it's working. Don't spin your
bit so fast that it gets hot and doesn't get a bite. You will just dull the
bit, and if there's seashell looking coloration on the bit, it's been over
heated. It's working perfectly when you get long spiral waste out of your
cuttings. You might have to grab hold of something, or have someone push on
your back to get some meat into the cutting end of the bit. That metal is
hot dipped galvanized, but it is not that hard.
