Upsetting the Border Police 2/5 (Bosnia-Croatia)

Shortly after crossing into Croatia we headed north along a track which followed a railway and river up a narrow, beautiful, wooded valley. Warning signs alerted us that this was a restricted area as the road crossed the border several times. But after taking advice from some locals who said that it was only 18km and the border police had recently passed through we decided to risk it.
It was a fantastic ride up a remote unpopulated track. After leaving the main track and crossing the river into Croatia over a narrow bridge we found the condition of the track deteriorate before it crossed back into Bosnia. We emerged into a farm yard where we caused great astonishment to a potbellied Bosnian farmer who saw us emerge from nowhere.
What we hadn't been told was that further up was a customs post. The Bosnian guy was fine but the Croatian border guard was unhappy that we had travelled along the track. Luckily he had no English so although he was using 'illegal entry' in his stream of words we just pretended that we didn't understand. Eventually when he realised we had cycled from Greece he forgot not only about our indiscretion but also to check our passports.
Soon after we camped down a side road on a hairpin bend as there was little flat ground. No traffic came through before 6.30 in the morning when a border patrol came past. We were up and having breakfast and after checking our passports he was only satisfied after we assured him that we had no intention of going to Bosnia.
