Whenever i go to trips with my frnds. We always make plan like yaar let's go to xyz place. Ok let's go. Call home, "dad/mom im leaving for xyz, will be back tomorow inshAllah". This is the real essence of the trips. As far as im concerned, i don't like the trip which u start planning. I believe, start ur journey, on ur way u'll have a lot lot of time to plan what to do.
Before this ramadhan, v 4 frnds left peshawar and we thought nothing where to go. During traveling on motorway, one of them said, let's go to lahore, the other two said muree. And at last we went to abbottabad and then nathiagali and covering whole galiaat to the pindi and next day back to peshawar. Trust me that was fun.
Last year we 3 frnd thought to visit KABUL. We left our homes for kabul and ended up going to nathiagali :S two totally different ways.
So remember my frnd, if u wana enjoy the trip, just start ur journey but always drive/ride safe
