I'll try and fit in the rides you mentioned. We passed the Locks twice, even turned around and went up the senic overlook to get a better view but when we saw that we had to walk out to see them, we just kept riding, it was too darn hot and humid for a walk . I'd love to get a close up and brief lesson on how it all works, Thanks for the offer. If I do go back it will be the 8th or 9th.
