Finding Local In-Person Property Auctions

[Alvin Grier]

I Google'd and couldn't find anything, so I thought I'd ask here.

I have a few questions regarding property auctions:

1. Do you have to pay a deposit or something in-order to attend a local in-person property property auction? 

...in other words, do you have to commit in some way to at least have some "intent" on buying something in order to attend such an event?

 ..or are all auctions done online nowadays?

2.   How do I find local in-person auctions?  I'd like to attend just to experience one, and to hopefully network.    It looks like the local tax auctions held by the local municipalities are all online now, from what I see.
