what a good job u've made of the state bonuses! 90% of them are good as is, which is some achievement on a map of this size and complexity.
as mentioned before, the large states with yellow airports will need bigger bonuses to compensate for both their vulnerability to attack and the delay in actually starting to pay out: +9 instead of +6 for california, +8 instead of +5 for texas, +5 instead of +3 for illinois, +7 instead of +5 for new york and +6 instead of +5 for georgia.
the corner location of florida just about compensates for the large number of cities that it has, so we can leave it at +4. for dc, +2 auto-deploy instead of +3 is probably more balanced, since it's initially accessible only from baltimore and will almost certainly form part of a strategy that combines dc with i-95.
for the bonuses that involve state capitals, perhaps include the star symbol to make it clear that dc doesn't count.
the road from plattsburgh to burlington has somehow gone through canada. straighten out the border to fix this.
