Hello i do not live in the Elhovo area although i have visited.
They have a few shops and a good market but personally i do not like the down trodden area.
The road from there to Burgas is dredfull full of holes in the road more of a dirt track an hour on that and you know you have been there and the locals in the area actually put signs up a few year ago saying **** off english!
The road to Yambol is better but again it is a long journey and it is full of heavy lorries from the boarders.
I am sure they could do better coming inland a little and then their are good roads good houses good facilities hospitals doctors etc and because of good roads they will only have the same distance to the coast and airport at Burgas 45 mins from our lovely little town of Straldja
Hope this has helped you
