Bobhouses to be off the lake by April 1st…

so any idea how many of these shacks actually fall into the lake each year? Is it really the desire to ice ish as long as possible? or is it just laziness?

good question
 

That is a really good question. i wonder how many bob houses are already at the bottom of the lake from previous years and if these are found to be sunken hazards in the more shallow part of the lake. Does Bizer or Duncan ever do any research to find out if there are bob houses causing hazards?
I can only imagine that this would be a very difficult task.

Bobing for bobbi's
 

I'll guess a couple get caught out every year but I don't think they usually end up as a hazard. Wave and wind action eventually sweep them, and more likely their pieces, onto shore somewhere. I don't recall finding anything that I would say came from a bob house on my shore though I have seen tree parts and dock pieces. It's these that I've also seen floating about in the lake during early boating season. You definitely want to be on the lookout in April and early May for these barely floating outdrive grabbers.

on a tangent - how many cars, if any, went through the ice this year ? Seems like we had a bumper crop last year and I don't recall hearing about any this season.
