Thanks for all your comments, I really appreciate your encouragement!
FireDawgStew - We live in Angus, it's known as "The Gateway to the Glens" - can't wait to get out there now I've conquered my fear! Next thing is to improve my ability!!
King Termite - thanks for your observations. You're right. The guys in the shop had it set higher but said to move it lower for just a wee while so my feet readily touch the ground while not confident - I am very short legged(!) and a scaredy cat

- then raise it back ASAP to where he set it to have a more comfortable ride.
