Finally, sharing an experience is appealing to more adventurous travelers. It might be that walking tour of street art in San Francisco.
I don't know exactly what "It might be that" is meaning.
Is there any different meaning when I use "It is that walking tour~" instead of " It might be that~"?
Also, in "It might be that walking~", is it right to use 'the' instead of that? if I can or not, what is different between them.
