well I went thru the ice a few times over the decades, first time was a on a MX bike(studded tires) crossing a frozen farm pond, that was spring feed from the middle of the pond
got about 3/4 of the way across and hit a soft spot that swallowed the front tire, stopped at the forks, but wasn't fun trying to get out,when your a small kid and a big bike
next Update NY, before trails were well maintained, a bridge crossing a small stream,about 6 ft across, but was dug deep for flood control) was washed out and folks were trying different places to cross at random, I gave it a go, and darn ski went under the bank on the other side rather than climbing up and out, and caused the front end to sink in about 4 ft of water!, back of sled was staying on top of ice, but when we jumped in to pull back and lift out, the whole thing caved in and we , 3 of us were now standing in 4 ft of water wresting the sled out!
wasn't a fun ride back to where were staying to dry off, but sled ran great never stalled and belt never slipped,. so IMO< got really lucky could have been worse!
next, LOL> went through ice on another pond on a ATv, just the back end broke through, and was sitting on frame, or was until trying to lift out, then the rest of the ice about whole thing caved in, and was soon standing in about 3 ft of water, just backed out after that as was almost on shore as is!
on a side note, NO motor vehicle involved, as a kid, growing up rural, there was a private lake about 10 miles away in a very remote area, only a 6 mile dirt road in and non one used it in winter time that held BIG fish, but was closed to fishing minus club members!
SO< me and a buddy decided to sneak into the place and try our luck ice fishing, we had NO real ice fishing gear, but we did have a big ax and a sledge hammer, and a lot of dumb in us both!
we hiked down to the lake, almost all down hill, in snow over our knee's(we figured for sure NO one else would be there or this dumb to go there in this snow and super cold, maybe 10 degree's out)
OH to be young and dumb! LOL
we made it there OK, shoved some snow off the ice about 20 ft from shore, and started smashing at the ice with the ax and sledge hammer, about the time we started to get a hole opened, the whole area we were standing on let loose and in we went, all our gear sank, and my my buddy was screaming we were going to die,
water was only about 6 ft deep(luckily) , and we managed to get yourself outs and then started out long walk out, about 10 minutes after we started out everything we were wearing was turning into a frozen ice rock, knee's on pants wouldn;t bend everything was stiff as could be, kept having to try and break things so they would bend!
that one I will never forget, it was a LONG cold walk out and honestly we got really lucky we didn;t go out into the middle of the lake to dig a hole, or might not be here to tell of things!, no one knew where we were,a s again we were not allowed there so, didn;t tell anyone
I fell thru the ice a few more times, but never anything like that, hunting swamps that never seem to freeze solid in all area's you find weak spots now and then, but normally just a wet food or likes
when I used to play off road a lot, I have burred a few trucks in water holes that ice stopped me, but normally backed out, or got pulled pretty fast
