Barred from Fort Mchenry.

I was shooting images at Fort Mchenry (USA National Park) and a park ranger baited me --by asking-- if she wanted one of the the images --could she buy one I thought for a second and said yes .I thought she meant, either she would like one or or maybe the gift shop may want one.. i was shooting multiple images on a tripod for hdr processing .

She then told me I couldn't shoot unless I purchased a permit and that I had to leave the premises I tried to say - I actually wasn't planning on selling the images, but thought if she really wanted one -- I would . She said that was her point.. I WOULD sell them if asked!! The permit could costs hundred's of dollarrs . She also said any Time she saw me there again with a camera -she would throw me out.
I think she was wrong.
Here rules the rules-see what you think
First nasty park ranger i ever met!!!
