We loose almost all of the site line if my neighbor decides to put up a sign, plant shrubs, let their tree overgrow, etc. and this is in the riskier direction from our stand point.Our argument was that we have 400' in the direction that has a flat straight away (theoretically faster traveling traffic) and have 3xx' in a direction that the traffic is traveling up hill with a shorter stopping distance and time, most traffic will be coming off of an Interstate off ramp which in theory they would be well under the speed limit when as they approach our property.To answer your question: I am undecided if I will do more development projects.
