Anyone heard of Hairy Coo Tours?

I have not taken a tour with Hairy Coo, but I have heard of them and seen their buses. They seem to sometimes use bigger buses (their site says from 16 to 57 people, so I suppose the bus size varies according to how many sign up). Rabbie's and also Discover Scotland (both of which I took one-day tours with) both use the smaller, 16-seat mini coaches. So that's a factor to consider if you prefer a small-group experience.

We took a Hairy Coo tour from Edinburgh to the Highlands. We enjoyed it a lot.

They are a reputable and well regarded tour operator. Be warned however that there could be up to 50 people on the tour and a lot of their publicity does show pictures of large coaches... Rabbies (and Timberbrush another well regarded company) just use mini buses so tour numbers will be limited to about 16. Consider the pros and cons of being on a big coach compared with a smaller one - particularly when it comes to comfort breaks and the additional time needed if larger num bers are involved...

There is a frequent train service between Glasgow and Edinburgh so I wouldn't worry too much about that.

a little help with the names. Nothing untoward with the name of Hairy Coo. Scots speak with a different accent to Londoners and a coo is a cow. They are called hairy because they have long ginger coloured hair - usually covering their eyes like an English sheepdog - and very long horns. Generally referred to as Hairy Coo.

So that's the name the company chose.

Profanity is in the mind of the beholder.

Rabbies tours are not tours by a group of Jewish rabbis. Rabbie is Scottish for Robby or Robbie, a diminutive of Rob or Robert.

That's the name used by the company, so Rabbies (or Rabbie's) Tours.

In terms of coo for cow, coo is the Scots word for cow similar to the Dutch koe. Many people code switch here between Scots and Scottish Standard English, which as can be guessed is the Scottish variant of standard UK English. It contains a lot of words from Scots. Scots, not to be confused with Scots Gaelic which is altogether different, is a separate language to English though it is very, very close in its evolution from the same Anglo Saxon West Germanic dialects of a millenium ago. It retains some elements English has lost, and there is a strong level of mutual comprehension between Scots and English.

You can find books written in Scots, it is largely written phonetically, something English is not, and the poems of Rabbie Burns are generally in Scots.

Scots Gaelic is not related except as an Indo European language. It has a word pronounced the same way, cù. It means dog.
