I used to do it often but got too busy with life. It's fun and relaxing, and as soon as my son is old enough to figure out what's going on, I'm sure we'll get back into it to have fun and get out of the house together.
my kids love going on tresure hunts the few times i done it. its amazing how many there are once you know about it. plus i found out what all the werdios in the field across from my house were always looking for.
