Oh, democracy is without a doubt very far removed from the common folk. How many people are actually in contact with the representative that is meant to represent them? And how possibly can this one representative fully take on board the opinions and wishes of the thousands of people they are meant to represent and then help to produce a coherent policy outcome with hundreds of other representatives who also each represent thousands of people? The opinions and wishes of our one individual are going to be incredibly insignificant to any policy outcome. This is perhaps one of the reasons for falling voter turnout across the western world (amongst numerous others, this was the subject of my dissertation thesis).
I think that by localising certain policy decisions these problems could be overcome. Here in Britain (I'm guessing there is something similar in the US) we have local councils with elected local councillors that represent a few hundred people and they make decisions on local issues with other councillors. But while better, representing even say 50 people would be quite challenging. And these elections still suffer from the point I made in my first post that they can be elected with say only 30% of the vote.
Personally I think many local issues could be localised even further and could be decided by direct democracy through referendums etc. As you mention parks etc would be included in this. Ideally all issues would be solved this way, but at the national level this is nowhere near possible. I do however think that proportional representation would be a fairer way of electing representatives at the national level and this I believe (various countries using PR instead of FPTP can be used as an example) would help increase voter turnout, although it wouldn't completely overcome the problem.
