This is the way. I grew up farther north (compared to now) with decent mounds from snow plows so it was just a matter of waiting for those and then tunneling into them.

These days I shovel the snow from a larger area to build my mound before tunneling. Kids love it regardless ☺️

I would like to do this with .com but has been held for several years so went with a newer TLD. It’s mostly been fine aside from occasional person whose mail provider sends me to spam or the very few who block me outright.
