I'm looking into a Caucasus trip visiting Turkey, Georgia and Armenia. A return flight from IST is far cheaper than a multi-city flight, so I'd like to get back to Istanbul without going over the same route I came in (through Georgia, which as I understand seems to be the only way to get to Armenia from Turkey)

Given local neighbour relations, what path can I take that includes all three but doesn't repeat any part of the journey ?

To return from Armenia, I see two equally unreliable options: 


Getting an Azerbaijan transit visa and crossing Naxchivan, but the Armenia-Azerbaijan border is apparently closed, and I'm afraid an Armenian stamp in my passport could complicate this passage. The Armenia-Azerbaijan border is closed, so that settles this issue.
Getting an Iranian visa in Georgia then boarding the Tehran-Istanbul train. This is risky as Canadian-Iranian relations aren't super right now, I've heard of people being denied visas.



Question: How can I insulate my garage?
Answer: The easiest way to insulate concrete block is to glue foam insulation board directly to the block. These boards come in 4 ft X 8 ft sheets and different R values. The other method is to build a wood or steel stud wall along the block to hold blanket style insulation along with electrical wiring etc. This method is a lot more work, but gives you a base to install sheetrock later on.

Depending on whether or not you want the attic area insulated or not, blanket or blown in insulation can be installed into the ceiling. ( this assumes you have a sheathed ceiling). Otherwise, you can install blanket insulation between the rafters. Depending on budget, sprayed in foam insulation is fantastic.   You may also want to look at some venting to help exhaust hot air during the summer months. I may add a few comments later, but here's a start.
