I'm not sure if the game will let me go back and do these other optional missions but I've definitely done most of the important ones and have 4 star with every post. I do have some Standard Deliveries and could probably deliver some more lost cargo but other than that, I've got nothing else. Will the game let me come back to do these or should I just finish them up now and then move on?

Also, another thing I wanted to ask; should I ditch the bike? It seems that it took away a shit ton of travel and immersion from the game and although It's fairly obvious it's the right choice (bridges and dirt roads indicate this also) it kind of feels a little game breaking. Avoiding any spoilers, do they take away the power from the bikes soon and make land you can't use the bike on?

Thanks in advance!
