[OSM-newbies] Two Questions

[Al Haraka]

Hello All,

I am very new to OSM.  I attended my first mapping party in my area,
and now I am trying to finish uploading some of the data from my
traces.  I only have a couple of waypoints, because I am slow like
that.  Now I am tagging my points on Potlatch and trying to learn for
myself.  Unfortunately, I have one situation I assume must be common
(and I am shameless n00b).  The other is kind of bizarre.

When I tagged a node that is a stand holding a garbage pale and a
recycling bin (I am not sure if this is specific to the US, or even
Maryland area).  To clarify, they are basically two bins right next to
each other held together by the same wooden post.  AFAIK, they are the
same item really.  Do I create a relation and have different amentiy
items (waste_basket and recycling) or do I add multiple tags to the
same node (amenity recycling;waste_basket)?  I have done the latter so
far, because the wiki implies, at least to me, amenities are for much
bigger fish in need of frying.

Later in the day, I was on a trail and there was a small little ditch
running along the side of this segment of the trail.  Someone had made
an ad hoc bridge to cross the ditch and allow people to utilize a
little clearing onto a local street.  How would I tag that?  It is
certainly not a bridge in the formal sense, and I am not sure what
else I could tag it is.  I thought some creative minds on the list
could enlighten.

That is all I got for now.  Thanks in advance guys.

Best,
