You may be able to dig a hole that easily in Florida but up here you'd need a backhoe.
Honestly, my dad lives in New Port Richey and I've done a bit of work at his place and I'm envious of how easy it is to dig fence post holes, or dig a new trench for a water line, but I do not envy the soil quality. Amending the soil (sand) there would be a full time job.
