Straits State Park, St. Ignace, Michigan
Humble yourselves, therefore, under God’s mighty hand, that He may lift you up in due time. Cast all your anxiety on Him because He cares for you. I Peter 5:6-7
A few minutes after 7:00am, I hurried Blaine out the door so we could ‘train’ and see the bridge in the early morning light. Fresh morning air is always the best, don’t you think? There’s just something about it . . .
Anyway, we rode to the observation area, took a look and went home for breakfast. Those of you who know Blaine are probably pretty fascinated with how I managed to get him to delay a meal. Guess I still have my charms. 😊
We walked quite a ways today, but it was easy walking. I even wore my “sight-seeing sandals”. Parking at a free lot in town, we hoofed it all the way to where our ferry dock was, just to check it out ahead of time. Former Boy Scout, remember? St Ignace has a really nice, long boardwalk along the water, that we only had to leave a couple of times because presumably, whomever the property owners were at that point, didn’t want a boardwalk taking up a portion of their land.
The only bad thing was, there wasn’t anywhere to sit and have lunch where the Jeep was parked, and by the time we returned, we were both pretty hungry. So we just sat inside. Still, it was an interesting lunch view today. 😊
Once we reached our destination, we walked back via the sidewalk. It was nice too!
Up next on our agenda, was a drive to the official Mighty Mac (as they call the Mackinac Bridge) observation area. It afforded us a fairly close up view, lots of flowers, and some interesting information which included a video of how they built it. Unfortunately, we couldn’t hear most of it because the acoustics were so bad in the building that anytime anyone talked, or ran the hand dryer in the bathroom, you couldn’t hear the video. But it was still intriguing to watch! Great videos of the men working! For you, I have pictures and clippings from the information boards that were around the room. And a list of facts I took from the internet. I put those at the end. Oh. And even though the name ends with a ‘c’, the pronunciation is ‘naw’ with a ‘w’. Why? It’s no wonder the English language is so difficult to speak and spell!
Then we went for a scenic drive on a dirt road, which was nice.
And lastly, a search for the Father Marquette Memorial. This missionary really made his mark in the UP – even though it was 350 years ago. Just goes to show you – – God uses all things, all people, and in all times and places to make Himself known.
I took pictures of a few snippets from the enormous amount of information on the story boards.
There was a limestone path at the memorial, so we walked that and stopped to take one last look at the bridge from the scenic overlook, and back home we went.
We’d heard the town did fireworks every Saturday in the summer, and even considered driving back over, but they don’t start until 10pm, and even though we’re retired, our bedtime’s still ten. However, we never imagined it would be such a long show! It lasted 15 minutes! Had we known, we most likely would have gone back to town. We did go outside, and were able to see about half of the show between the trees. It was close enough we could hear all the booms, which is really what makes fireworks. I’ve seen them without the sound, and it’s just not the same. Pretty. But no excitement.
