Even the greatest start small

 Ahhh...The great outdoors...

 even the longest journey starts with the smallest of steps.....a journey of exploration...

 where strange creatures are seen....

 ..water hazards crossed....

 ..giant dogs avoided...

 ..some will try and deter you, make you doubt your goal...

 .....in the end trust your judgement.....

 ..until Grandma tells you that's far enough, its time to go home.....

..Hurrumph! Bet this never happened to Ranulph!
